Abstract

The invention discloses an ELISA (Enzyme-Linked Immuno Sorbent Assay) detection kit for bovine coronavirus. The ELISA detection kit is characterized in that purified BCoV-CD isolate recombinant pET-32a-N protein is used as coating antigen, reaction conditions are optimized, and an indirect ELISA diagnosis method for detecting bovine-serum characteristic N protein antibodies. The ELISA detection kit disclosed by the invention has the beneficial effects that escherichia coli is adopted for prokaryotic expression, the raw-material sources are wide, the preparation is easy, the standardization iseasy, and the production and detection processes are safer and more reliable, so that the ELISA detection kit is suitable for being promoted and used in basic units.

Description

technical field

[0001] The invention relates to the technical field of virus detection, in particular to a bovine coronavirus ELISA detection kit. Background technique

[0002] Diarrhea is one of the most serious diseases of newborn calves. Calves are at the greatest risk of developing diarrhea within the first month of life. The incidence of diarrhea decreases with age. Viruses, bovine coronavirus and enterotoxigenic Escherichia coli (K99) are related to four major enteric pathogens. Bovine coronavirus is the most important pathogen causing adult bovine winter dysentery (WD) and calf coronavirus diarrhea (CD). Through the investigation of antibody detection in animal serum, it was found that there is a high positive rate of bovine coronavirus in the three northeastern provinces.

[0003] Generally speaking, there are many detection methods for bovine coronavirus, including general methods such as EM, IEM, IF, IFA, HA, RT-PCR, RTFQ PCR, ELISA and many other methods, althou...
