The preferred embodiment of the present invention is described below with reference to attached drawing.
<Embodiment 1>
In the embodiment 1, include in the multiple fluorescent materials for keeping wavelength of fluorescence mutually different and cell is detected Substance is combined and differentiates the cell for locally lying in situation of tested substance according to the multiple fluorescence generated from fluorescent material In information acquisition method, the present invention is applied.In the embodiment 1, tested substance is NF- κ B.NF- as transcription factor κ B are present in the state of foring complex with I κ B in cytoplasm, it is believed that pass through point of the I κ B caused by various stimulations Solve and be transferred to the inside of core.In the embodiment 1, it is parsed as follows：Using NF- κ B as tested substance, fluorescence is used Matter particularly identifies, and according to the fluorescence from fluorescent material, judgement NF- κ B are present in which of cytoplasm and core.In addition, Tested substance can also be protein, the molecule other than NF- κ B.For example, tested substance can also be to turn other than NF- κ B The factor is recorded, for example, it can be STAT (Signal Transducer and Activator of Transcription, letters Number transduction and activating transcription factor), NFAT (nuclear factor of activated T cells, the core of activating T cell The factor), HIF (hypoxia-inducible factor, hypoxia inducible factor).In addition, tested substance can also be mRNA, microRNA.In addition, " multiple fluorescent materials is made to be combined with tested substance " refers to being not necessarily the quilt of the same race for including in cell Detection substance each molecule all combined with multiple fluorescent materials, multiple fluorescent materials particularly with it is at least part of of the same race The molecule of tested substance combines.It is locally lain in core in addition, the differentiation for locally lying in situation is not limited to tested substance In still locally lie in the differentiation in cytoplasm.For example, in the case where having shape for lugs as nerve cell, also may be used To differentiate whether tested substance locally lies in the front end of protrusion.
As shown in Figure 1, cellular informatics acquisition methods include the steps that step S1~S4.Hereinafter, illustrating that operator uses energy The flow cytometer imaged to fluorescent image is reached with the processing unit that can be parsed to the image of camera shooting to execute Fig. 1 Cellular informatics acquisition methods the case where.Each step of Fig. 1 can also be executed by the processing in cellular informatics acquisition device. Then, with reference to after Fig. 5, illustrate the structure in the case that cellular informatics acquisition device carries out each step of Fig. 1 and processing.
In step sl, operator is extracted with the mutually different mark of fluorescent material 11,12 of wavelength of fluorescence from examinee The NF- κ B for including in cell.For example, as shown in Fig. 2, via an antibody and secondary antibodies, in fluorescent material 11,12 and cell Including NF- κ B combine.Fluorescent material 11,12 can both be combined by multiple antibody with NF- κ B, can also be by anti- A part for body or the whole of antibody and combined with NF- κ B.In addition, in step sl, operator's wavelength of fluorescence and fluorescence The different fluorescent material 13 of substance 11,12, the core for including in marked cells.
Fluorescent material 11,12,13 is fluorchrome.Fluorescent material 11,12,13 is respectively structured as illuminated wavelength X 1, λ 2, the fluorescence of mutually different wavelength period is encouraged when the light of λ 3.That is, the wave of the light for encouraging fluorescence from fluorescent material 11~13 Length is set to mutually different.In this way, modulating sample by step S1.In addition, being mRNA, microRNA in tested substance In the case of, fluorescent material is combined via nucleic acid probe with tested substance.
In step s 2, operator drives flow cytometer, makes the examination for including the cell identified with fluorescent material 11~13 Sample is flowed into flow cell, to the light of the 1~λ of cell irradiation wavelength X 3 flowed in flow cell so that from fluorescent material 11~13 Generate fluorescence.
As shown in Fig. 2, when to the laser of 1~λ of cell irradiation wavelength X 3, difference is generated respectively from fluorescent material 11~13 Wavelength period fluorescence.Filter member 21 makes the fluorescence of the wavelength period B1 generated from fluorescent material 11 pass through, and interdicts wavelength period Light other than B1.By filter member 21, the fluorescence of the wavelength period B1 generated from fluorescent material 11 is detached.Filter member 22 make the fluorescence of the wavelength period B2 generated from fluorescent material 12 pass through, the light other than blocking wavelength period B2.Pass through filter member 22, the fluorescence of the wavelength period B2 generated from fluorescent material 12 is detached.Filter member 23 makes the wave generated from fluorescent material 13 The fluorescence of long section B3 passes through, the light other than blocking wavelength period B3.By filter member 23, from the wavelength of the generation of fluorescent material 13 The fluorescence of section B3 is detached.
Here, with high power to the laser of cell irradiation wavelength X 1, with low-power to the laser of cell irradiation wavelength X 2.It is logical The laser to cell irradiation wavelength X 1 with high power is crossed, having passed through the fluorescence of the wavelength period B1 of filter member 21 becomes high-strength Degree.By the laser with low-power to cell irradiation wavelength X 2, having passed through the fluorescence of the wavelength period B2 of filter member 22 becomes Low-intensity.
In step s3, processing unit obtains 3 according to the fluorescence generated from fluorescent material 11~13 for each cell Fluorescence information.Flow cytometer has the fluorescence difference of wavelength period B1~B3 for making to detach by filter member 21~23 The structure for being imaged onto the acceptance part being made of photographing element and obtaining the image based on each fluorescence.Processing unit is according to fluidic cell The image pickup signal of the acceptance part output of instrument, obtains the image of the fluorescence of the high intensity based on wavelength period B1, based on wavelength period B2's The image of the image of low intensive fluorescence and fluorescence based on wavelength period B3 is as fluorescence information.
About the fluorescence of wavelength period B1~B3, it both can individually be imaged, can also be led to respectively by 3 acceptance parts 1 acceptance part is crossed to be imaged.Optical system is configured to, and is taken the photograph to the fluorescence of wavelength period B1~B3 by 1 acceptance part The fluorescence of wavelength period B1~B3 is imaged on the light-receiving surface of acceptance part in different regions as in the case of.
As shown in figure 3, in the case of ought being the cell that NF- κ B are locally lain in core, in step s3, such as figure is obtained As 31,32.Image 31 is the image of the fluorescence of the high intensity based on wavelength period B1, and image 32 is the low-intensity based on wavelength period B2 Fluorescence image.In image 31,32, region 33 existing for core is set.Region 33 is from based on being given birth to simultaneously with image 31,32 At wavelength period B3 fluorescence be is generated from core fluorescence image acquisition.
In the case where being that NF- κ B locally lie in the cell in cytoplasm, in step s3, such as acquisition image 41, 42.Image 41 is the image of the fluorescence of the high intensity based on wavelength period B1, and image 42 is based on the low intensive glimmering of wavelength period B2 The image of light.Region 43 existing for core are all set in image 41,42.Region 43 is from based on being generated simultaneously with image 41,42 Wavelength period B3 fluorescence image obtain.
In the case where being the few cell of discovery amount of NF- κ B, according to image 31, the intensity of fluorescence is appropriate, and in core Occurs difference in fluorescence intensity between cytoplasm, so can differentiate that NF- κ B are locally lain in the region of core 33.Another party Face, according to image 32, the intensity of fluorescence is too low, so can not differentiate that NF- κ B are locally lain in the region of core 33.On the other hand, Be NF- κ B discovery amount more than cell in the case of, according to image 41, the intensity of fluorescence is excessively high, thus as core with it is thin Do not have discrepant state between cytoplasm in fluorescence intensity.Therefore, it is impossible to differentiate that NF- κ B are locally lain in the region of core 43 and ratio Which of the wide cytoplasmic region in the region 43 of core region.On the other hand, according to image 42, the intensity of fluorescence is appropriate, And difference is generated in intensity between core and cytoplasm, so can differentiate that NF- κ B are locally lain in the region 43 than core Wide cytoplasmic region.
In the case where NF- κ B are locally lain in cytoplasm, NF- κ B are distributed in the cell in a manner of surrounding core.That is, When observing cell on imaging direction, NF- κ B are also distributed in the front of core.Therefore, in the figure of the fluorescence based on high intensity In 41, strong fluorescence is also generated in the region of core by being distributed in the NF- κ B of front of core.Therefore, it in image 41, deposits The trend in cytoplasm is still locally lain in core can not suitably differentiate that NF- κ B are locally lain in.In contrast, in base In the image 42 of low intensive fluorescence, although the NF- κ B of the front by being distributed in core also generate fluorescence in the region of core, But the intensity of the fluorescence is low.Therefore, even if can be fitted if in the case that NF- κ B are locally lain in cytoplasm in image 41 Locality, which differentiates, locally lies in situation.
In addition, in the case where NF- κ B are locally lain in core, a part of NF- κ B is distributed in cytoplasm, but more than half It is distributed in core.Therefore, in the image 31 of the fluorescence based on high intensity, strong fluorescence is generated from the NF- κ B being distributed in core, It can suitably differentiate that NF- κ B are locally lain in core.On the other hand, it in the image 32 based on low intensive fluorescence, comes from The fluorescence for being distributed in the NF- κ B in core is excessively weak, so in the presence of can not suitably differentiate that it is in core or local that NF- κ B are locally lain in The trend being present in cytoplasm.
In this way, according to the amount of the NF- κ B as intracellular tested substance and distribution, the part for differentiating NF- κ B Existing appropriate intensity is different.
Therefore, be set to can be appropriate in the cell that NF- κ B locally lie in core for the power of the laser of wavelength X 1 Ground differentiates that the NF- κ B as shown in image 31 are locally lain in core.The power of the laser of wavelength X 2 is set to locally deposit in NF- κ B It is in the cell in cytoplasm suitably differentiate that the NF- κ B as shown in image 42 are locally lain in cytoplasm.Exist as a result, As in the cell for differentiating object, no matter NF- κ B are locally lain in which of core and cytoplasm, 2 can be used At least one party in image differentiates locally lying in for NF- κ B.
Back to Fig. 1, in step s 4, operator with reference to the high intensity based on wavelength period B1 fluorescence image and be based on The image of the low intensive fluorescence of wavelength period B2 differentiates the distribution situation of the NF- κ B as tested substance.Specifically, behaviour Author selects in the image of the image of the fluorescence of the high intensity based on wavelength period B1 and the low intensive fluorescence based on wavelength period B2 , the image for locally lying in position that can differentiate NF- κ B, according to the image, differentiate in the cell NF- κ B locally lie in In which of core and cytoplasm, locally lie in situation.It can also replace locally lying in situation, differentiate that NF- κ B are distributed in Which position, such as intracellular distribution.
As described above, in the embodiment 1, by adjusting 2 generated from the fluorescent material 11,12 for identifying NF- κ B Fluorescence, the one party become in the image of the fluorescence based on high intensity and the image based on low intensive fluorescence can suitably be sentenced Determine the state of NF- κ B locally lain in.Therefore, operator can precisely parse the distribution in cell according to 2 images Diversified NF- κ B.Specifically, can precisely differentiate that the NF- κ B's in cell locally lies in situation, i.e. NF- κ B is locally lain in which of core and cytoplasm.
In addition, in the embodiment 1, it is also contemplated that following situation：In the case that even if NF- κ B are locally lain in core, by It is more in the amount of NF- κ B, so as the excessively high state of the intensity of the fluorescence of image 31, the intensity for becoming the fluorescence of image 32 is appropriate State.In this case, also by using the intensity of the fluorescence image 32 appropriate can to differentiate that NF- κ B are locally lain in core In.In addition, it is also contemplated that following situation：Even if in the case where NF- κ B are locally lain in cytoplasm, since the amount of NF- κ B is few, So the intensity state appropriate of the fluorescence as image 41, becomes the too low state of the intensity of the fluorescence of image 42.In the feelings Under condition, it can differentiate that NF- κ B are locally lain in cytoplasm also by the intensity of fluorescence image 41 appropriate is used.In this way, According to embodiment 1, according to 2 images, no matter the amount of NF- κ B how much, can precisely differentiate the NF- κ B in cell Locally lie in situation.
Here, vascular endothelial cell is removed from the inner wall of blood vessel and is flowed into blood.The stripping of vascular endothelial cell, is removed Other than the stimulation caused by inflammation generates, due also to the variation of the pressure caused by compressing etc. also generates.Due to In the vascular endothelial cell removed by the stimulation caused by inflammation, NF- κ B tend to locally lie in core, due to because of inflammation Stimulation other than caused stimulation and in the vascular endothelial cell removed, NF- κ B tend to not locally lie in core.According to reality Mode 1 is applied, can precisely differentiate locally lying in for NF- κ B as described above, so can be according to as signaling molecule Whether NF- κ B locally lie in judge to remove at these in core due in inflammation caused by stimulation and the stripping that generates From can determine vascular endothelial cell, whether there is or not activations.As a result, for example, can judge the stripping of vascular endothelial cell be due to Compressing when blood sampling and generate or generated for main cause with disease etc., have meaning clinically.
Can also be by the laser of the middle power of the wavelength different from wavelength X 1, λ 2, the image of the fluorescence of intensity in acquisition. That is, 3 fluorescent materials that wavelength of fluorescence can also be used mutually different identify NF- κ B, to 3 laser of cell irradiation so that from 3 A fluorescent material generates the different fluorescence of intensity to obtain the image based on each fluorescence.It is different by the intensity from fluorescence as a result, 3 images in use optimal image, can precision differentiate locally lying in for NF- κ B better.From tested substance The intensity of the fluorescence of generation can also be 4 grades or more, can also be directed to 1 cell and obtain based on 4 or more intensity 4 or more images of fluorescence.
In turn, in step s 4, operator obtains examination according to the situation that locally lies in of each cell differentiated as described above In the cell for including in sample, NF- κ B locally lie in the ratio of the cell in privileged site.Specifically, if will differentiate The quantity that the cell in core is locally lain in for NF- κ B is set as N1, will be determined as NF- κ B and locally lies in the cell in cytoplasm Quantity be set as N2, then operator is by formula below, obtains that core locally lies in rate and cytoplasm locally lies in rate.In addition, In step S4, operator can also locally lie in rate instead of core and cytoplasm locally lies in rate and obtain core and locally lie in number and thin Cytoplasm locally lies in number.
Core locally lies in rate={ N1/ (N1+N2) } × 100
Cytoplasm locally lies in rate={ N2/ (N1+N2) } × 100
In step s 2, the image of each fluorescence is obtained using flow cytometer as described above, but not limited to this, also may be used To use microscope, the image of each fluorescence is obtained as fluorescence information.That is, can also be obtained from fluorescent material by microscope The fluorescent image of 11 high intensity generated is produced from the low intensive fluorescent image of the generation of fluorescent material 12 and from fluorescent material 13 Raw image corresponding with core.

4. being detected using flow cytometer
As the flow cytometer that can obtain fluorescent image, ImageStreamX Mark II Imaging have been used Flow Cytometer(Merck Millipore).The sample according to above-mentioned 3 modulation is set to be flowed into the circulation of the flow cytometer Chi Zhong has irradiated the laser of wavelength 488nm, 647nm, 405nm to the sample flowed in flow cell.Wavelength 488nm, The laser of 647nm, 405nm are corresponding with above-mentioned wavelength X 1, λ 2, the laser of λ 3.The laser of wavelength 488nm, 647nm, 405nm are penetrated It is respectively 55mW, 10mW, 120mW to go out power.2 kind iridescent of the laser irradiation of wavelength 488nm, 647nm to mark NF- κ B Thus element produces the fluorescence of high intensity and low intensive fluorescence respectively.The laser irradiation of wavelength 405nm to nuclear staining pigment and Produce fluorescence.
In above-mentioned flow cytometer, via the filter member of transmission peak wavelength section 505nm~560nm, to passing through wavelength The fluorescence that the laser of 488nm generates is imaged, and the fluorescent image of high intensity is obtained.Via transmission peak wavelength section 642nm~ The filter member of 740nm, the fluorescence generated to the laser by wavelength 647nm image, and obtain low intensive fluorescence Image.Via the filter member of transmission peak wavelength section 430nm~505nm, fluorescence that the laser by wavelength 405nm is generated into Row camera shooting, obtains fluorescent image corresponding with core.In addition, to the sample flowed in flow cell, wavelength is irradiated and has been set Laser between 430nm~480nm.Via the filter member of transmission peak wavelength section 430nm~480nm, which is transmitted Light after cell is imaged, and obtains bright field image.In addition, in above-mentioned flow cytometer, pass through filter member Acceptance part is suitably incident on the light for becoming the wavelength period of object etc. to remove the light of unwanted wavelength period.In addition, Bright field image is obtained in this verification, but not limited to this, scotopia field picture can also be obtained.
With reference to Fig. 4 (a), illustrate the image obtained by above-mentioned detection.
" bright field " indicates the bright field image of cell." fluorescence of high intensity " and " low intensive fluorescence " is based on respectively The image of the fluorescence of the high intensity generated from the fluorchrome for identifying NF- κ B and based on from the fluorchrome for identifying NF- κ B The image of the low intensive fluorescence generated." fluorescence from core " is based on being produced from the nuclear staining dyed to core with pigment The image of raw fluorescence." synthesis " is image obtained from 4 images in synthesis left side.5 transversely arranged images are from 1 The image that cell obtains.The figure that " fluorescence of high intensity ", " fluorescence from core ", " low intensive fluorescence " and " synthesis " indicates Seem that image obtained from grayscale is carried out to acquired coloured image for convenience.At " fluorescence of high intensity ", " come from In the image that the fluorescence of core " and " low intensive fluorescence " indicate, white part indicates that the intensity of fluorescence is strong.
Shown in epimere in the case of cell, the intensity of the image based on low intensive fluorescence is too low, so being difficult to sentence Other NF- κ B's locally lies in.On the other hand, the intensity of the image of the fluorescence based on high intensity is appropriate, so NF- can be determined as κ B are locally lain in core.Shown in hypomere in the case of cell, the intensity of the image of the fluorescence based on high intensity is excessively high, institute To be difficult to differentiate locally lying in for NF- κ B.On the other hand, the intensity of the image based on low intensive fluorescence is appropriate, so can NF- κ B are determined as to locally lie in cytoplasm.
5. core locally lies in the calculating of rate
It is visual by being carried out to acquired image, differentiate locally lying in for NF- κ B for each cell.With above-mentioned step Rapid S4 has been carried out similarly the differentiation.That is, the region of core is set according to the fluorescent image from core, by the area other than the region of core Domain is as cytoplasmic region.In addition, the case where the fluorescence intensity for thinking core is the about 2 times or more of cytoplasmic fluorescence intensity Under, it is determined as the NF- κ B in the cell and locally lies in core, be less than cytoplasmic fluorescence intensity in the fluorescence intensity for thinking core About 2 times in the case of, be determined as the NF- κ B in the cell and locally lie in cytoplasm.
With reference to Fig. 4 (b), illustrate to be directed to and with 131 cells that above-mentioned flow cytometer identifies differentiated that the part of NF- κ B is deposited Result.
The quantity for being determined as locally lying in the cell in core is 44, is determined as locally lying in the cell in cytoplasm Quantity is 87.It can not differentiate that the quantity of the cell locally lain in is 0.It is 44/131=34% that core at this time, which locally lies in rate,.
Here, explanation has differentiated the comparative example 1 locally lain in and according only to low-intensity according only to the fluorescent image of high intensity Fluorescent image differentiated the comparative example 2 locally lain in.In the case of comparative example 1, it is determined as locally lying in thin in core The quantity of born of the same parents is 42, and the quantity for being determined as locally lying in the cell in cytoplasm is 10.The intensity of fluorescence is excessively high, so can not Differentiate that the quantity of the cell locally lain in is 79.It is 81% that the core of comparative example 1, which locally lies in rate,.In the case of comparative example 2, sentence The quantity that the cell in core Wei not locally lain in is 16, and the quantity for being determined as locally lying in the cell in cytoplasm is 84. Fluorescence intensity is too low, so can not differentiate that the quantity of the cell locally lain in is 31.The core of comparative example 2 locally lies in rate 16%.
As described above, according to this verification it is found that as Embodiment 1 according to 2 different fluorescent images of intensity In the case that differentiation is locally lain in, about the cell that can not be differentiated in the case of Comparative Examples 1 and 2, it can also differentiate NF- κ B's It locally lies in.In addition we know, in the case where differentiation as Embodiment 1 is locally lain in, the cell that can not be differentiated is few, so It can precisely differentiate locally lying in for the NF- κ B in cell.Therefore, according to embodiment 1, can will can not differentiate The quantity of cell inhibits relatively low, precisely differentiates locally lying in for NF- κ B.As a result, for example, even if being extracted from examinee Cell it is few in the case of, also can precisely differentiate that the part of NF- κ B is deposited while the cell for guaranteeing to differentiate .
In the embodiment 1, the differentiation as the distribution situation of tested substance shows and differentiates that the part of NF- κ B is deposited In the example of situation, but in the case where the amount of the molecule of tested substance changes, it can also differentiate the amount of the molecule. In this case, operator identifies molecule with fluorescent material 11,12, processing unit is according to the intensity generated from fluorescent material 11,12 2 different fluorescence obtain image.In the case that operator is more than the amount of molecule, differentiated using low intensive fluorescent image Amount, in the case where the amount of molecule is few, using the fluorescent image of high intensity come the amount of differentiation.Thereby, it is possible to precisely differentiate The amount of molecule.

Next, with reference to the flow chart of Fig. 8, illustrate the place that the step S4 of Fig. 1 is carried out by cellular informatics acquisition device 100 The case where reason.
As shown in figure 8, in step s 11, processing unit 110 drives sample modulation portion 120, in the same manner as the step S1 of Fig. 1, It is tried with the core for including in 13 marked cells of fluorescent material to modulate with the NF- κ B for including in fluorescent material 11,12 marked cells Sample.In step s 12, processing unit 110 makes sample flow into flow cell 200, and light source 301~304 is driven by driving portion 140, right The cell irradiation light flowed in flow cell 200.In step s 13, processing unit 110 passes through 501~503 pairs of wavelength periods of acceptance part The fluorescence of B1~B3 is imaged, and is imaged to the light of wavelength X 4 by acceptance part 504.Then, the acquisition unit of processing unit 110 111 image pickup signals exported according to acceptance part 501~504, obtain image.
In step S14, from high intensity and low intensive fluorescent image, selection can be into for the analysis unit 112 of processing unit 110 The image for the differentiation that row is locally lain in.Specifically, analysis unit 112 selects the fluorescent image of high intensity and low intensive fluorogram The image of the brightness of the intensity such as image entirety of fluorescence as in, being obtained from image within a predetermined range.It is glimmering as a result, The intensity of light terrifically big image, fluorescence intensity terrifically can not in the same manner as small image and the image 32 of Fig. 3, image 41 Locally lying in for NF- κ B is differentiated, so the image used from differentiation removes.
In addition, analysis unit 112 selects in high intensity and low intensive fluorescent image, the analysis object position of cell The difference of the fluorescence intensity in cell other than the fluorescence intensity and analysis object position image bigger than scheduled threshold value.In embodiment party In formula 1, analysis object position is core.That is, the difference of the fluorescence intensity in selection core and the fluorescence intensity of the cell outside core is than predetermined The big image of threshold value.The image 32 of the difference of the fluorescence intensity in core and outside core small image and Fig. 3, image 41 are same as a result, Ground can not differentiate locally lying in for NF- κ B, so the image used from differentiation removes.
Next, in step S15, analysis unit 112 is sentenced using the image selected in step S14 for each cell NF- κ B's in other cell locally lies in.That is, the part that analysis unit 112 calculates the NF- κ B at the analysis object position of cell is deposited The ratio of the amount of locally lying in of NF- κ B in measuring versus cell entirety.For example, the figure that analysis unit 112 selects in step S14 As in, by the fluorescence intensity in the region of the intensity of the fluorescence in the region of core divided by cell entirety.Analysis unit 112 is in division knot In the case that fruit is 2 or more, it is determined as NF- κ B and locally lies in core, in the case where result of division is smaller than 2, be determined as NF- κ B are locally lain in cytoplasm.The value of judgement result of division is not limited to 2, can also be other values.
In addition, in the case of having selected 2 images in step S14, in step S15, for the image of two sides, as above The acquirement result of division and differentiate locally lie in.In addition, in step S14 in the case of non-selected image, in step S15 In, locally lying in for the cell is considered as " can not differentiate ".
In step s 16, analysis unit 112 according to the differentiation of all cells handled as a result, calculating above-mentioned core office Portion there are number, cytoplasm locally lie in number, core locally lies in rate and cytoplasm locally lies in rate.In step S17, processing unit 110 is aobvious by calculated numerical value in step s 16, the differentiation result of image and each cell obtained for each cell etc. It is shown in display unit 150.Specifically, the picture 161 including the above is shown in display unit 150 by processing unit 110.
As shown in figure 9, picture 161 has region 161a, 161b.Region 161a shows that core locally lies in number, cytoplasm office Portion locally lies in rate there are number, core and cytoplasm locally lies in rate.Region 161b shows locally lying in for image and NF- κ B Differentiate result.In the 161b of region, the image of the differentiation in step S15 for locally lying in is enclosed in solid line, to know It locally lies in differentiation and has used the image.
The fluorescence information obtained in step s 13 can also be the waveform signal for the fluorescence intensity for indicating to change over time. In this case, in optical detection portion 130, as acceptance part 501~503, the photodetectors such as photomultiplier are respectively configured. 3 photodetectors receive the glimmering of the fluorescence of the high intensity of wavelength period B1, the low intensive fluorescence of wavelength period B2 and wavelength period B3 Light, respectively output indicate the waveform signal of the intensity of each fluorescence.
As shown in Figure 10, the waveform signal that analysis unit 112 is exported according to photodetector, be NF- κ B discovery amount it is few In the case of cell, such as obtain chart 51,52, be NF- κ B discovery amount more than cell in the case of, such as obtain chart 61、62.In addition, the waveform signal that analysis unit 112 is exported according to photodetector, obtains chart corresponding with core.Analysis unit 112 According to the chart of the core obtained simultaneously with chart 51,52, the width W1 of waveform corresponding with core is set in chart 51,52, according to The chart of the core obtained simultaneously with chart 61,62 sets the width W2 of waveform corresponding with core in chart 61,62.
According to chart 51, the peak value of fluorescence is between threshold value Sh1, Sh2, and there are waveforms in width W1 corresponding with core Peak value, so analysis unit 112 can be determined as NF- κ B and locally lie in core.On the other hand, according to chart 52, fluorescence Peak value is smaller than threshold value Sh1, so analysis unit 112 can not differentiate locally lying in for NF- κ B.According to chart 61, the peak value ratio of fluorescence Threshold value Sh2 is big, so analysis unit 112 can not differentiate locally lying in for NF- κ B.On the other hand, according to chart 62, the peak value of fluorescence Between threshold value Sh1, Sh2, there are the recess of waveform in width W2 corresponding with core, so analysis unit 112 can differentiate It is locally lain in cytoplasm for NF- κ B.It therefore, in this case, also can in the same manner as the case where using image as shown in Figure 3 It is enough precisely to differentiate locally lying in for NF- κ B by 2 different fluorescence of intensity.
