Description
Technical field
The present invention relates to a kind of chemiluminescence immune detection reagent kit that detects Clenbuterol, be used for detecting Clenbuterol content or residual quantity in animal derived food such as animal tissue, internal organ, blood, urine and feed, the feedstuff.Belong to the immunology detection field.
Background technology
(Clenbuterol CLB), is commonly called as clenbuterol hydrochloride to Clenbuterol, is a kind of beta-stimulants.Because of it can improve the ratio of meat with the fat of lard type animal, and can quicken growth of animal, and extensively be made an addition in the animal feed, and can be in animal body residual.Yet this medicine has serious adverse to the people.Gently then cause the heartbeat and the rhythm of the heart undesired, but heavy then cardiac trigger disease.At present, China and many countries have forbidden that it uses as feed addictive.
Aspect the detection method of Clenbuterol, method at present commonly used comprises high performance liquid chromatography (HPLC), gas chromatography-mass spectrography (GC-MS), liquid chromatograph mass spectrography (LC-MS), Capillary Electrophoresis, enzyme linked immunosorbent assay analysis method (enzyme linked immunosorbent assay, method such as ELISA).
1, high performance liquid chromatography (HPLC) is used for the detection of Clenbuterol:
The HPLC method has and detects degree of accuracy height, characteristics that false positive rate is low, and the lowest detection that detects residual of kelengtelu is limited to 1～15 μ g/kg, domestic with high performance liquid chromatography as the half authenticity method that detects residual of kelengtelu.It is more loaded down with trivial details that the major defect of HPLC method is that instrument costs an arm and a leg, operates, length consuming time, testing cost costliness; And the selection of the extraction conditions of sample also has considerable influence to detection sensitivity and accuracy in earlier stage.
2, gas chromatography-mass spectrography (GC-MS) is used for the detection of Clenbuterol:
GC-MS sensitivity is very high, and false positive rate is low.The major defect of this method is that sample needs derivatization to handle complicated like this early stage.Though can provide more structural information through the sample of derivatization treatment in mass spectrum, derivatization can produce a plurality of different products and cause the partial loss of sample, causes the deviation of experimental result.
3, liquid chromatograph mass spectrography (LC-MS) is used for the detection of Clenbuterol:
LC-MS does not need derivatization treatment to sample, can detect urine, blood, liver, hair and eyeball sample.This method reaches 0.1 μ g/kg to the lowest detectable limit of Clenbuterol, and the MS coupling if LC connects with two can further improve signal to noise ratio (S/N ratio).The shortcoming of LC-MS is the same with GC-MS, and complex operation step needs expensive instrument, so general with the affirmation means of doing positive findings.
4, Capillary Electrophoresis is used for the detection of Clenbuterol:
Capillary zone electrophoresis method separation efficiency can reach millions of theoretical cam curves, operates fast and conveniently, and required sample size is few.But the required instrument costliness of this method, and can detect the sensitivity that the minimum residual quantity of Clenbuterol does not reach other method.
5, enzyme linked immunosorbent assay analysis method (ELISA) is used for the detection of Clenbuterol:
Enzyme linked immunosorbent assay analysis method is one of current application immunoenzyme technics wide, the most with fastest developing speed, and major advantage is to detect rapidly, and sample pre-treatments is simple, and detection system is simple to operate, and cost is low, is convenient to simultaneously detect on a large scale.Its ultimate principle is, antigen (or antibody) is adsorbed on the solid phase carrier, enzymic-labelled antibody (or antigen) and corresponding antigen (or antibody) reaction, be combined in enzyme on the immune complex when running into corresponding substrate, can the catalytic substrate hydrolysis, oxidation or reduction and produce coloring matter, the depth of color is directly proportional with corresponding antibody (or antigen) amount, so can come qualitative or quantitative antibody (or antigen) by the degree of dye-forming reaction.The ELISA detection method mainly comprises double antibody sandwich method, indirect method, competition law etc.Double antibody sandwich method mainly is applicable to the comlete antigen that molecular weight is bigger, and law of competition is applicable to the less small-molecular weight haptens in antigen decision site.Because Clenbuterol is micromolecular compound (relative molecular mass is less than 5000), belongs to haptens, competitive enzyme-linked immune absorption method therefore commonly used is measured.
6, the principle of work of chemiluminescence immunoassay detection technique and characteristics
The chemiluminescence immunoassay detection technique is different from enzyme linked immunosorbent assay analysis method, and it is the product of chemoluminescence method and immunoassay combination, therefore has the high sensitivity of chemiluminescence detection technology and the high specific of immuno analytical method simultaneously.
The ultimate principle of chemiluminescence immunoassay is similar to ELISA, and difference is that the reaction system of enzyme labeling thing is a chemiluminescence reaction.HRP (horseradish peroxidase) and luminol or derivatives thereof system are exactly one of reaction system of using always, and adding reinforcing agent in this luminescence system can increase chemiluminescence intensity, and keep stable in the long period, thus the sensitivity that improves immunoassay greatly.China petty official transmit etc. (petty official is transmitted etc., the analytical chemistry research notes, 2005,33 (5): 699-702) the indirect competition chemiluminescence immunoassay method of setting up detects Clenbuterol in the pig urine sample, the actual detected scope is 0.04～25.8 μ g/kg.This method adopts Clenbuterol-egg albumin solution bag by the black check-out console, seals with egg albumin.Added Clenbuterol standard solution and testing sample to bag by the black check-out console during detection, add antibody of clenbuteral (is anti-) then, room temperature incubation 30min; The antiantibody (two is anti-) that adds horseradish peroxidase-labeled then, room temperature incubation 30min again; Add luminous substrate liquid at last, and measure luminous intensity with chemiluminescence detector.The shortcoming of this method is to use one anti-and two anti-(wherein two anti-be enzymic-labelled antibody) simultaneously, all needs to carry out incubation reaction after two kinds of antibody addings, has prolonged detection time.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of chemiluminescence immune detection reagent kit that detects Clenbuterol is provided.Fast and convenient, highly sensitive, advantages such as the detection cost is low, good reproducibility, high flux that kit of the present invention has, the residual quantity that can be used for Clenbuterol in animals urine, blood sample, tissue, internal organ and the samples such as feed, feedstuff detects.
For achieving the above object, the present invention utilizes the ultimate principle of the specific immune response of antigen and antibody to realize.Chemiluminescence immunoassay is the product of chemoluminescence method and immunoassay combination, therefore has the high sensitivity of chemoluminescence method and the high specific of immunoassay simultaneously.In entire reaction course, Clenbuterol content is high more in the sample, and luminous intensity is weak more in the reaction system; Otherwise Clenbuterol content is few more in the sample, and luminous intensity is high more.
