[0032] The preparation method of this CLB molecularly imprinted polymer biomimetic antibody of the present invention, its steps are as follows:

[0033] (1) Preparation of CLB derivatives:

[0034] Clenbuterol hydrochloride was dissolved in dichloromethane solvent, triethylamine was added and methacryloyl chloride was added dropwise in the dichloromethane solution, and the mixture was reacted overnight at room temperature. After the reaction, wash the reaction solution with saturated sodium bicarbonate solution, separate the organic phase, wash the water phase twice with dichloromethane, combine the organic phases, dry over anhydrous sodium sulfate, and remove the organic solvent under reduced pressure with a rotary evaporator. The residue was purified with a silica gel column using petroleum ether-ethyl acetate mixed solvent as eluent to obtain CLB derivatives.

Abstract

The invention relates to a preparation method of clenbuterol hydrochloride molecularly imprinted polymer biomimetic antibody, which aims to solve the problems of low specificity and template molecule leakage of existing CLB molecularly imprinted polymer biomimetic antibody. The steps of the method are as follows: (1) preparing CLB derivatives; (2) preparing CLB molecularly imprinted polymer bionic antibodies. The CLB molecularly imprinted polymer biomimetic antibody prepared by the present invention adopts covalent bond polymerization, non-covalent bond way to adsorb the target substance, has stable physical and chemical properties, strong specificity, fast adsorption rate, no leakage of CLB molecules, and is suitable for bionics Establishment of immunoassay detection method.

Description

technical field [0001] The invention relates to a preparation method of a biomimetic antibody, in particular to a preparation method of a covalent clenbuterol hydrochloride molecularly imprinted polymer biomimetic antibody. Background technique [0002] Clenbuterol (CLB) is an adrenal nerve stimulant, which has been clinically used to prevent and treat bronchial asthma, chronic bronchitis and other diseases. CLB is a kind of "lean meat extract" with high bioavailability, which can change the metabolic pathways in animals, promote protein synthesis in muscles and bones, accelerate growth, improve carcass quality, and increase lean meat percentage. However, CLB is easy to accumulate in the animal body, and the residual amount in the lung, liver, kidney and other organs, muscle and fat tissue is relatively large, and the residual time is relatively long, and it can accumulate in the human body through the food chain, causing toxic and side effects on the body. The main manifes...
