Description

[0001] The present invention relates to an analyzing system for biological material,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biological sample measurement apparatus, and more particularly, to a method and apparatus for measuring a plurality of quantification targets by detecting light emitted through chemiluminescence generated by an antigen- And a biometric sample measuring device.

This research was supported by the Ministry of Commerce, Industry and Energy, the Ministry of Commerce, Industry and Energy, and the project for cooperation with the Ministry of Commerce, Industry and Energy (2013, development and commercialization of arrhythmia diagnosis / treatment equipment, Project No. R0002625).

Recently, there is an increasing demand for on-site diagnostics to directly measure the concentrations of the components to be detected at the site of use and to immediately reflect the results. Particularly, a specific requirement for a biological sample measuring device capable of quickly and easily diagnosing and analyzing human diseases is increasing in daily life and medical field.

A variety of methods can be used to measure biological samples. Among them, there is a chemiluminescence measurement method by measuring chemiluminescence radiating from a chemical reaction process between a biological sample and a reagent. The chemiluminescence assay is widely used for the analysis of biological samples through the measurement of luminescence generated in the antigen-antibody reaction and the reaction process of the target substance and the aptamer.

The antigen-antibody reaction is a very specific reaction in which the antibody acts only with the antigen of interest. That is, an antibody or an antigen that binds to a specific antigen or antibody. When the antibody to be detected is an antigen, a specific antibody is used. In this case, an enzyme is bound to the specific antibody. When an antigen is bound to a specific antibody, the substrate is reacted with the enzyme bound to the specific antibody, so that the antibody is colored and the concentration is measured from the change in color. Currently, antibodies bound to enzymes are widely used for the quantitative analysis of viruses, and enzyme-linked immunosorbent assays (ELISA), which is a representative method thereof, are used. An enzyme-linked antibody assay is a quantification method based on an antigen-antibody reaction using an enzyme as a marker. These analytical methods are useful for assaying antigens from unknown samples or for quantifying antibodies.

1 schematically shows an enzyme-linked antibody assay. As shown in FIG. 1, an antigen 23 acting on the first antibody 21 is attached to a tube 10 to which a first antibody 21 is attached. To bind the antigen (23) to the first antibody (21). The enzyme 27 is conjugated with the second antibody 25 acting on the antigen 23. The second antibody 25 acts on the antigen 23 bound to the first antibody 21 and binds thereto. Then, the second antibody (25) which is not bound to the antigen (23) is washed and removed. A coloring or a light emitting reagent is injected into the tube 10, and the concentration or color development or luminescence is measured.

According to the procedure described above, the concentration of the antibody acting on the antigen or the antigen is measured. However, since there is no automated apparatus for measuring the concentration by adding the coloring or the luminescent reagent, there was an inconvenience in measuring the concentration, There is a problem that can not be continuously measured. This problem also applies to the luminescence measurement generated in the reaction process of the target substance and the aptamer.

The second opening may further include a thermometer to shut off the power supplied to the heating unit 1804 when the temperature reaches a predetermined temperature while measuring the temperature. The power to the heating unit 1804 is cut off and the third motor 1808 is operated so that the tray 1801 slides outside the second opening in a state as shown in Fig. At this time, when the target 1806 is positioned in front of the front sensor 1803, the operation of the third motor 1808 is stopped by the operation signal of the front sensor 1803. The front sensor 1803 and the end sensor 1805 can also act as an on / off switch to cut off or connect the power supplied directly to the third motor 1808.

When the enzyme tube 2001 is inserted into the through hole 1382 of the rotating body 1380 disposed inside the guide wall 1360, the lower portion of the enzyme tube 2001 is located in the attachment groove 1384, Exposed to the outer surface.

The first driving sensor 1372 or the second driving sensor 1374 senses the identification terminal 1389 provided under the rotating body 1380 and transmits a signal to the controller 171 so that the rotating body 1380 Can be adjusted by the rotation change shown in Figs. 8 to 11, the rotation change shown in Figs. 12 and 13, and the lowering height of the insertion portion 1340 can be adjusted.

The enzyme tube 2001 is inserted into the rotating body 1380 and the lid 120 is closed to block the entrance of external light and then an analysis command is inputted through the input unit 179. Then, The first pump 1321 and the second pump 1322 are operated to pump the reagents contained in the first and second containers from the left side of FIG. 4 into the third container to be mixed in the third container. The third pump 1323 pumps the reagent, and the fourth pump 1324 pumps the reagent contained in the fourth container and supplies it to the charging unit 1340.

And the reagent contained in the fourth vessel may be hydrogen peroxide (H2O2).

When the reagent is injected as described above, the reagent reacts due to the presence of the enzyme 27, and light is emitted. The emitted light is detected by the first sensor 1355, which is an optical sensor, converted into a digital signal, 171 and stored in the storage unit 177 while being calculated as the concentration of the antigen 23 in comparison with the data previously input to the storage unit 177. [

When the mounting member 1347 rises, the first motor 1379 operates to rotate the rotating body 1380, and the third driving sensor 1376 rotates to the rotating terminal 1387 provided below the rotating body 1380, The first motor 1379 stops. The rotating body 1380 is also stopped and the adjacent enzyme tube 2001 is positioned below the charging unit 1340 and the charging unit 1340 is lowered so that the reagent And the emitted light of the reagent is sensed by the first sensor 1355 and the detected light amount is converted into a digital signal and is calculated by the arithmetic unit 175 in terms of the concentration and stored in the storage unit 177. The process of calculating the operation and concentration of the charging unit 1340 and the pump unit 1320 is the same as described above, and therefore, the repetitive description will be omitted.

When it is necessary to vary the input height according to the rotating body 1380, The first tube sensor 1344 may include a second tube sensor 1346 in addition to the first tube sensor 1344 to detect the identification terminal 1389 in the first drive sensor 1372, The rotation of the second motor 1353 is stopped when the member 1347 is detected and the rotation of the second motor 1353 is detected by the second tube sensor 1346 when the second driving sensor 1374 detects the identification terminal 1389. [ The rotation of the second motor 1353 is stopped to adjust the input height of the input unit 1340. [

In another embodiment, the biological sample measurement apparatus 100 may measure a biological sample by measuring chemiluminescence generated during the reaction of the target substance and the aptamer. More specifically, it is as follows. In the tube 2001, at least one selected from the group consisting of phenylglyoxal, phenylglyoxal derivative, and combinations thereof may be contained in the tube 2001 as a reaction material. For example, as the phenylglyoxal derivative, acetyl, oxy, methoxy, C1-C6 linear alkyl or C1-C6 branched alkyl may be bonded to a phenyl ring as a substituent. As another example, the phenylglyoxal derivative may be at least one selected from the group consisting of phenylglyoxal, 3-methoxyphenylglyoxal, 4-methoxyphenylglyoxal, 3,4-dimethoxyphenylglyoxal, 3,5-dimethoxyphenylglyoxal, 3,4,5-trimethoxyphenylglyoxal Either one may be used. For convenience of explanation, TMPG will be mainly described as the reaction material accommodated in the tube 2001.

In the first container, a secretion such as saliva, blood or urine of a person having a biological sample as a reagent may be quantitatively injected. The biological sample may be, for example, a protein, a microorganism, a virus, an organic substance, an inorganic substance, a chemical substance, or the like. The inorganic material may be, for example, sodium (Na) or potassium (K) present in the urine.

The second container may contain a reagent containing guanine. In this case, the reagent contained in the second container may be a DNA or RNA sequence containing guanine. The DNA or RNA sequence containing the guanine may be an aptamer capable of binding with the biological sample. Aptamers are ligands of interest, i.e., oligonucleotides designed to bind to the biological sample. That is, the aptamer can be selected as appropriate to bind with the selected biological sample. Fluorescent labels can be attached to the DNA or RNA sequences. By a chemiluminescent resonance energy transfer (CRET) generated between the energy intermediate generated in the course of the reaction between guanine and phenylglyoxal or a guanine and a phenylglyoxal derivative and the fluorescent label bound to the DNA or RNA sequence, The intensity of light generated during the reaction between the liquid material 10 and the second liquid material 20, the pattern of the emitted light, and the lifetime of the light can be changed. It is possible to adjust the intensity of the light, the pattern of the emitted light, the lifetime of the light, etc., which are generated through the selection of the fluorescent markers. These fluorescent labels include, for example, pacific blue, fluorescein, 6-FAM, Cy3, Cy3.5, Cy5, Cy5.5, HEX, TET, VIC, NED, JOE, ROX, Texas Red, Phodamine Green, Rhodamine Red, And a combination of these may be used.

The fourth container contains at least one selected from tetra-n-methyl ammonium phosphate, tetra-n-ethyl ammonium phosphate, tetra-n-propyl ammonium phosphate (TPA) Reagent may be contained. For convenience of explanation, the TPA will be mainly described as the reagent contained in the fourth container.

The biological sample contained in the first container is mixed with the reagent contained in the second container, i.e., the aptamer, in the third container. After the mixing, the mixed solution of the biological sample and the aptamer contained in the third container is injected into the tube 2001 together with the TPA contained in the fourth container and reacted with the reaction material contained in the tube 2001, that is, TMPG, to chemiluminesce. That is, the guanine contained in the aptamer reacts with the TMPG contained in the tube 2001 to chemiluminesce. At this time, the TPA functions as a catalyst for changing the reaction rate or the reaction pattern of chemiluminescence. In this case, the degree of chemiluminescence varies depending on how much the biological sample and the aptamer react with each other, and the emitted light is measured by the first sensor 1355, which is a photosensor. Therefore, by measuring the degree of chemiluminescence, the concentration of the biological sample contained in the first container can be measured. Since the operation of the remaining biological sample measurement apparatus 100 is sufficiently inferred from the above description, a detailed description thereof will be omitted for convenience of explanation. Accordingly, the biological sample measurement apparatus 100 disclosed in this specification can measure the intensity of light, the pattern of light, the lifetime of light, etc., which are generated differently depending on the presence or absence of the biological sample, Can be diagnosed.

According to the biological sample measurement apparatus 100 of the present invention as described above, it is possible to accurately inject the light emitting reagent into each tube while rotating the sample tube 1380 with a plurality of tubes at a predetermined angle, It is possible to rapidly measure the luminescence and to inject the reagent into the tube precisely since the injecting part 1340 moves upward and downward when the emitting reagent is injected, Since the side surface of the mounting groove 1384 of the body 1381 of the rotating body 1380 is formed as the mirror surface 1386, it is possible to accurately detect the small light emission, thereby improving the accuracy of analysis. The temperature of the tube can be adjusted, and the temperature of the tube can be increased by providing the heating means 180, The reagent container can be fixed without being shaken while the structure of the mounting portion 1310 is simplified.
