ELISA detection method and reagent kit for bluetongue viral antigen

Abstract

The invention discloses an ELISA detection method and a kit of blue-tongue virus antigen. The detection method uses the monoclonal antibody of anti-blue-tongue virus VP7 protein as dual-anti sandwich ELISA detection method of a coating and enzyme-marked antibody; and the kit comprises the monoclonal antibody of the anti-blue-tongue virus VP7 protein of the coating and enzyme-marked antibody. The kit and the detection method can be used for detecting the blue-tongue virus antigen, have higher specificity and sensitiveness, can be used in large-scale forserological detection, is suitable for epidemiological investigation and has wide application prospect.

Description

technical field [0001] The invention relates to a double-antibody sandwich ELISA detection method and a kit for bluetongue virus (BTV) antigen in serum (plasma). Background technique [0002] Bluetongue disease (BT) is caused by bluetongue virus (BTV) and is a viral infectious disease of ruminants transmitted by Culicoides. The World Organization for Animal Health (OIE) lists it as a reported animal disease (OIE Terrestrial animal health code, 13th ed.2004. Terrestrial Animal Health Code. Thirteenth Edition, Office International des Epizooties, Paris.), and is listed as a class of animal in my country Diseases (http: / / www.ivdc.gov.cn / ). The incubation period of infected animals is generally 5 to 12 days, and the course of disease is generally 6 to 14 days. The average morbidity rate of ruminants after infection is 30-40%, and the mortality rate is 20-30%, among which the mortality rate of sheep is 80%-90%. [0003] In recent years, outbreaks of bluetongue have occurred all...
