Embodiment 1

[0062] The preparation of embodiment 1 kit components

[0063] 1. Antigen Synthesis

[0064] a. Synthesis of hapten

[0065] Abamectin was synthesized by dibromosuccinic acid method and glutaric anhydride method to synthesize abamectin drug hapten.

[0066] b. Immunogen synthesis

[0067] The abamectin drug hapten and human serum albumin are coupled by a mixed anhydride method to obtain an immunogen.

[0068] The preparation process of the immunogen: take 2 g of abamectin drug hapten and dissolve it in 30 ml, 50% N, N-dimethylformamide solution, then take 0.5 ml of isobutyl chloroformate and dissolve it in 5 ml of anhydrous di Add it to the hapten solution and stir it at room temperature for 4 hours, take 32g of carrier protein and dissolve it in 70ml pH9.6 carbonate buffer, then add human serum albumin dropwise to the hapten and stir overnight at 4°C. The reacted artificial antigen was dialyzed against 0.2M phosphate buffer for 7 days, and the solution was changed 3 to 4 ...

Abstract

The invention provides an enzyme immune agent box for detecting avermectin drugs which comprises: enzyme mark plate which coats sheep-resistance mouse-resistance antibody, enzyme mark antigen, avermectin drugs antibody, avermectin standard solution, base material color developing solution, compression cleaning liquid, ending solution and compression diluting solution. The invention also discloses a method for applying the detecting method, which comprises: first doing sample front process, then using the agent box to detect, at last analyzing the detected result.

Description

technical field [0001] The invention relates to an ELISA kit and method for detecting abamectin drugs in animal tissues. Background technique [0002] Avermectins (AVMS) belong to macrolide antibiotics, commercialized avermectins are a mixture of the two most active homosystems among eight compounds with very similar chemical structures, Avermectins The dihydrogen reduction product of ivermectin is another important antiparasitic drug. [0003] Abamectin has a strong inhibitory effect on the vast majority of parasitic nematodes and arthropods with important economic value. It is a major breakthrough in the research of antiparasitic drugs in the past ten years. At present, abamectins have begun large-scale production and application. [0004] However, the excessive use of abamectin drugs makes them highly residual in animal-derived foods, causing the human body to develop drug resistance and causing certain harm to the human body. Therefore, it has been used in limited qua...
