Assistant engineer has, be mainly used for immunoblot experiment automatic sample, liquid feeding, concussion incubations, reagent adding, cleaning, air-dried, result are taken pictures and
The operations such as area of computer aided interpretation.
Immunoblotting is also known as Western blotting, is specifically binding come certain in detection of complex sample according to antigen-antibody
The method of kind albumen, high specific and sensibility with high resolution and solid-phase immunoassay.Immune-blotting method method is wet
Immobilization matrix film is flexible, easily operated;The large biological molecule of immobilization can be equably close with various immunological probes, will not picture
Gel is obstructed by aperture like that;Immunoblotting assay only needs a small amount of reagent, and resource is greatly saved;Multiple copy can be made simultaneously
Shellfish is used for a variety of analyses and identification.
The flow of immune-blotting method approximately as:
After protein to be detected is transferred on blotting membrane, blotting membrane is closed, then incubated with Primary antibodies, cleaning, then
Antibody incubation, cleaning are connect with two level again, is detected according to colorimetric method or chemiluminescence method, interpretation of result.
Specifically, primary antibody is the antibody of testing protein specificity, and secondary antibody is marked radioactive isotope or is combined with
Fluorescent material, gold particle, or coupled with enzymes such as-HRP or-AP.Typically now use includes radioactive labels autography technology, ratio
The secondary antibody of the substrates and combination-HRP or-AP such as color detection, chemiluminescence, bioluminescence, chemiluminescence, fluorescence and Immuno gold detection
It incubates.In this system, after substrate is added, its generation colored precipitate (colorimetric detection) of enzymatic or chemiluminescence, fluorescence etc.
Then optical signal uses film or CCD, Fluorescence Scanner to carry out signal collection.
Testing protein generates colourful signal after being combined with specific antibody.The signal of colorimetric detection is colored precipitate substance.
What CL and BL detected is the optical signal that reaction itself generates.Difference lies in substrate source differences for the two.Change
The enzymatic preparation learned in fluorescence detection method can send out fluorescence signal.The signal of fluoroscopic examination, autoradiograph, Immuno gold detection
All it is that labeled secondary antibody generates.The secondary antibody of fluoroscopic examination is marked with fluorophor;The secondary antibody mark of autoradiography
There is radioactive isotope;The secondary antibody of Immuno gold detection indicates gold, and signal can be precipitated by silver and be strengthened.
In some embodiments, film bar groove 14 has 50, and sample tube groove 162 has 50.
In this way, the full-automatic immunoblotting instrument 100 in present embodiment can be carried out at the same time more projects, albumen is improved
The efficiency of quality detection.
Specifically, the full-automatic immunoblotting instrument 100 in present embodiment includes 10 peristaltic pumps and 10 fluid passages,
To ensure that the efficiency of protein detection.In some embodiments, sample tube groove 162 is in double setting, and first
The sample tube groove 162 of row and 162 stagger setting of sample tube groove of second row.
In this way, when sample-adding syringe needle 124 moves between double sample tube 164, it will not accidentally encounter sample tube 164, subtract
The error for having lacked immune-blotting method experiment, improves the efficiency of test.
In some embodiments, interpretation structure 126 is additionally provided on first movement arm 122, interpretation structure 126 includes electricity
128 photographic system of lotus coupling device (CCD).
In this way, for relatively various chemiluminescence detection technologies, CCD imagings have be easiest to, be most accurate, fireballing spy
Point.CCD camera has the very wide range of linearity, different according to the pixel depth of system, and the range of linearity is from 2.0-4.8 etc..
That is even if signal strength variation reaches tens million of to tens thousand of times, still can accurately measure.CCD systems can be experiment
Record, analysis, the shared and storage of data are brought convenience, and without buying the various consumptions needed for film development regularly
Material.Another advantage of CCD is to reach the sensitivity technique limit in the relatively short time.
In some embodiments, the long side direction of the length on X and film bar groove 14 in a first direction of interpretation structure 126
Equal length.
In this way, when judging the blotting membrane in structural scan film bar groove 14, the face for judging structure cover film bar groove 14 is increased
Product so that interpretation structure 126 move it is primary after can interpretation to more blotting membranes, improve interpretation efficiency, also improve and sweep
Retouch the accuracy of interpretation.
In some embodiments, length of the interpretation structure 126 on the direction vertical with first direction X is more than or equal to film
The length of the short side direction of bar groove 14.
In this way, interpretation structure 126 move it is primary after can simultaneously in interpretation more multimembrane bar groove 14 blotting membrane, reduce first
The movement of moving arm 122 improves the efficiency of interpretation.
In some embodiments, it is additionally provided with the second moving arm 121 on moving track 12, is set on the second moving arm 121
It is equipped with multiple suction waste fluid channels 123 and multiple reagent adding channels 125, waste fluid channel 123 is inhaled and is set along the orientation of film bar groove 14
It sets, reagent adding channel 125 is arranged along the long side direction of film bar groove 14.
Specifically, inhaling waste fluid channel 123 can move in the vertical direction, to ensure to inhale waste fluid channel 123 by film bar groove 14
Interior waste liquid absorbs completely, avoids omitting, be had an impact to subsequent operation.
The orientation for inhaling waste fluid channel 123 along film bar groove 14 is arranged, and can handle the waste liquid in multiple film bar grooves 14 simultaneously,
Improve waste liquid infiltration rate.Reagent adding channel 125 is arranged along the long side direction of film bar groove 14, ensure that test solution can be uniformly added into
Into film bar groove 14, convenient in subsequent detection, detection liquid energy and test fluid to be checked uniformly contact, and ensure the reliable of testing result
Property.
In some embodiments, inhaling waste fluid channel 123 has 4, and reagent adding channel 125 has 10.
In this way, the time that waste liquid is drawn in 4 imbibition channels greatly shortens.Similarly, the time for adding reagent also greatly shortens.
In addition, 4 are inhaled waste fluid channels 123 and ensure that the experiment condition of each film bar groove 14 is consistent, from ensuring the accurate of experimental result
Property.
In some embodiments, the height of sample rack 16 is less than the height of the top surface of film bar groove 14, and sample tube 164 is put
After setting on sample rack 16, the top of sample tube 164 is less than 14 place plane of film bar groove.
In this way, when sample-adding syringe needle 124 moves between film bar groove 14 and sample rack 16, sample tube 164 will not be touched,
It avoids polluting sample tube 164, sample-adding syringe needle 124 on the move is also avoided to damage sample tube 164.
In some embodiments, sample-adding syringe needle 124 is replaceable.
In this way, sample-adding syringe needle 124 can be needed replacing according to experiment to be disposably loaded syringe needle 124 or being permanently loaded syringe needle
124, achieve the purpose that save resource and ensures working specification.
In the present embodiment, operator edits the program of experimental project on the control device in advance, before experiment starts
Bar code on scanned samples test tube 164, and sample tube 164 is placed sequentially on sample rack 16, trace item is placed on film
In bar groove 14;After starting instrument, it is automatically performed whole experiment process;Finally taken pictures by CCD, area of computer aided interpretation experiment knot
Fruit, generates and print result is reported.
In the full-automatic immunoblotting instrument 100 of present embodiment, air-dried unit 127 is additionally provided on the second moving arm 121.
Air-dry the rate of drying that unit 127 accelerates film bar groove 14.
