Description
Technical field
The invention belongs to field of medical examination, specifically, the present invention relates to a kind of fluorescent quantitation and detect the immunochromatographytest test kit of salbutamol (SAL) and the preparation method of fluorescence labeling liquid.
Background technology
Salbutamol, chemical name are 1-(4-hydroxyl one 3 hydroxymethyl phenyls)-2 one (uncle's fourth is amino) ethanol, are a kind of medicines that can combine with adrenergic receptor, are mainly used in treatment asthma, bronchial spasm etc. clinically.SAL is used as feed addictive, can significantly promote growth of animal, increase feed conversion rate and lean meat percentage mouth, long-term excess is used, and then can in animal tissue, accumulate, and the people can poison after having eaten this animal product in initiation.Early 1990s, a lot of excitant poisonings took place in Europe, and China also had a lot of poisonings to take place so far from 1998, so EU countries and China all make respective specified and forbids that it uses as feed addictive.But ordered about by economic interests, still have a large amount of illegal phenomenons of using.Therefore supervision, detect in the animal product with feed in excitant just become the problem demanding prompt solution that concerns the consumer health.
What Chang Zuowei growth accelerator used in the beta-stimulants is Clenbuterol, but along with the increasing to the Clenbuterol inspecting force, illegal user begins to turn to other substitutes.Because the growth promoting function of SAL and Clenbuterol is more or less the same, its elimination time ratio Clenbuterol in animal body is short, toxicity a little less than, therefore, SAL just becomes Clenbuterol topmost substitute afterwards.But domestic immunologic detection method research for SAI also is in the starting stage; Detection method such as gas one matter coupling method (GC-MS), high performance liquid chromatography (HPLC) and liquid one matter coupling method (LC-MS) etc. to beta-stimulants; Have accurately and reliably, repeatability is strong etc. a bit; But the shortcoming of these methods is outstanding equally, like instrument costliness, complicated operation, portable difference etc., thereby is unfavorable for applying on a large scale and high throughput testing.Therefore, this patent is set up a kind of easy, reliable, quick, detection method that Sensitive Detection SAL is residual, so that monitor the SAI in the animal tissue is residual.
Application number is the patent of invention of CN201010235592.7; Relate to beta-stimulants Ractopamine, salbutamol binary detection test-strips and preparation method thereof; Can effectively solve the problem that can detect beta-stimulants Ractopamine, salbutamol fast, easily simultaneously; Method is: be disposed with diversion spun glass, carrier spun glass, nitrocellulose membrane and absorbent wool pulpboard above the base material PVC plate from back to front; Diversion spun glass, carrier spun glass and be coated with the overlay film of being made up of anterior coverlay and rear portion coverlay above the absorbent wool pulpboard can be used for detecting simultaneously beta-stimulants Ractopamine, salbutamol.But the method also is not easy realization for higher sensitivity, and cannot be as quantitative test.
Application number is the patent of invention of CN200810249803.5; A kind of chemical luminescence ELISA detection kit of salbutamol is disclosed; Comprise box body, being located at polyclonal antibody, the ELIAS secondary antibody that each hole in the box body is coated with the ELISA Plate of the envelope antigen of processing with Clenbuterol and ovalbumin coupling and is located at the salbutamol in the box body is antibody, salbutamol series standard solution, concentrated phosphoric acid salt buffer, concentrated cleaning solution, the luminescent solution of the goat-anti rabbit of HRPO mark.That its kit has is highly sensitive, good reproducibility, easy characteristics fast and accurately; Compare with traditional colorimetric ELISA method; Sensitivity can improve an one magnitude, is expected in the salbutamolum residue of animal derived food (like milk appearance, animal tissue's appearance) and urine sample detects, play a significant role, still; This method also not the long period reaction, be unfavorable for on-the-spot test.
Summary of the invention
The objective of the invention is to overcome the defective of above-mentioned prior art, a kind of with low cost, easy and simple to handle, a kind of fluoroscopic examination salbutamol kit that sensitivity is high is provided.
For realizing above-mentioned purpose, the present invention has taked following technical scheme:
A kind of fluorescent quantitation detects salbutamol (SAL) immune chromatography reagent kit, and this kit comprises test strips and fluorescence labeling liquid, and said test strips is overlapped in order to stick on the base plate by sample pad, cellulose nitrate coated film, thieving paper and constitutes; Said cellulose nitrate coated film comprises detection zone (T district) and Quality Control district (C district); Said detection zone is coated with SAL-BSA conjugate (salbutamol-bovine serum albumin(BSA) conjugate), and said Quality Control district encapsulates anti-rabbit igg; Contain fluorescence labeling SAL antibody and fluorescence labeling rabbit igg in the said fluorescence labeling liquid.
Preferably, said cellulose nitrate coated film Quality Control district (C district), the coating buffer concentration of anti-rabbit igg is 0.2～2.0mg/ml, consumption is 90 μ l/27-35cm.
Preferably, said cellulose nitrate coated film detection zone (T district), the coating buffer concentration of salbutamol conjugate is 0.2～2.0mg/ml, consumption is 90 μ l/27-35cm.
More preferably, said cellulose nitrate coated film Quality Control district, the coating buffer concentration of anti-rabbit igg is 0.2～0.5mg/ml; The coating buffer concentration of SAL-BSA conjugate (being salbutamol antigen) is 0.2～1.5mg/ml, and consumption is 90 μ l/27-35cm.
