Abstract

The invention provides an enzyme linked immunosorbent assay kit for detecting ribavirin. The kit comprises an elisa plate coated with a coating antigen, a ribavirin standard substance solution, an enzyme-labeled antibody, substrate developing liquid, a stop solution, a scrubbing solution and reconstitution fluid. The coating antigen is a ribavirin coupled antigen, and the enzyme-labeled antibody is an enzyme-labeled ribavirin antibody. The invention further discloses a method for detecting ribavirin through the enzyme linked immunosorbent assay kit. The method comprises the steps that firstly, sample pretreatment is conducted; then, detection is conducted through the kit; finally, a detection result is analyzed. The enzyme linked immunosorbent assay kit can be used for detecting the content of ribavirin in animal tissue samples, and is easy and convenient to operate, low in expenditure, high in sensitivity and suitable for screening a large number of samples, and on-site monitoring is achieved.

Description

technical field [0001] The invention relates to an enzyme-linked immunoassay detection technology, in particular to an enzyme-linked immunoassay kit for detecting ribavirin, which can qualitatively and quantitatively detect the residual amount of ribavirin in animal tissues. Background technique [0002] Ribavirin (RBV, ribavirin) is a highly efficient broad-spectrum antiviral nucleoside drug, which has a good inhibitory effect on a variety of DNA and RNA viruses, and has multiple action sites, high efficacy, and low toxicity. , It is not easy to produce drug resistance and has few side effects. It has been used in the treatment of many viruses. Clinically, it has a high curative effect on the treatment of influenza, various respiratory syncytial viruses, viral hepatitis, human immunodeficiency virus and epidemic hemorrhagic fever. However, such drugs are prone to drug resistance, causing virus mutations, and long-term use can cause toxic effects on body cells. The most pro...
