Embodiment 1

[0025] The preparation of embodiment 1 kit components

[0026] (1) Antigen synthesis

[0027] A. Synthesis of Morphine Artificial Antigen

[0028] Weigh 500 mg of morphine raw material, add 50 mL of benzene and 1 g of succinic anhydride, and heat to reflux for 8 h. Install the evaporating device and evaporate the benzene. The precipitate was washed with anhydrous ether and anhydrous ethanol respectively, and the residue was vacuum-dried to obtain powdery substance 6-succinic acid-morphine. Weigh 20 mg of the above powdered substance and dissolve it in 10 ml of PBS buffer (phosphate buffer), add 30 ul of triethylamine, then add 30 ul of isobutyl chloroformate, and react for half an hour. Weigh 20 mg of BSA and dissolve it in PBS buffer solution, add the above reaction solution, stir and react overnight, dialyze for 3 days, centrifuge in a high-speed refrigerated centrifuge, collect the supernatant to obtain the morphine antigen.

Abstract

The invention discloses an enzyme linked immunosorbent assay kit for detecting drugs in urine, saliva, blood and hairs in the technical field of the prohibited goods detection and analysis as well as a detection method of the drug testing enzyme linked immunosorbent assay kit. The kit comprises a drug standard substance solution, a drug specificity antibody, an elisa plate which is coated with the drug specificity antibody, a drug antigen enzyme marker, a color developing agent, concentrated washing liquor, a termination solution and a sample dilute solution. The enzyme linked immunosorbent assay kit has characteristics of high specificity, high sensitivity, high accuracy and the like and plays an important role in drug testing.

Description

technical field [0001] The invention belongs to the technical field of detection and analysis of contraband, in particular to an enzyme-linked immunosorbent assay kit for detecting drugs in urine, saliva, blood and hair and a detection method thereof. Background technique [0002] Under the influence of the international drug epidemic, the drug situation in my country is very severe. As of the end of May 2013, the statistics show that there are currently 2.22 million drug users in China, and there are also many hidden drug users. Therefore, in order to prevent and punish drug-related crimes, protect citizens' physical and mental health, and maintain social order, it is necessary to establish accurate, reliable, and highly sensitive drug testing. [0003] Most opioid drugs are hallucinogenic, narcotic, and have analgesic effects, mainly including opium, marijuana, heroin, morphine, 6-monoacetylmorphine, and codeine. Amphetamine-type drugs refer to a class of synthetic compou...
