Abstract

The invention discloses a monoclonal antibody for detecting a new coronavirus. The formula of the monoclonal antibody for detecting the new coronavirus comprises the following components by weight: 1-3mg of antibody purified by protein G for ascetic fluid preparation, 0.5-1.5 mg of an antibody purified by antigen for ascetic fluid preparation, 1-3mg of an antibody purified by ammonium sulfate precipitation for ascetic fluid preparation, 1-3mg of an antibody purified by protein G for cell supernatant enlarge cultivation, 0.5-1.5 mg of an antibody purified by antigen for cell supernatant enlarge cultivation; the monoclonal antibody for detecting the new coronavirus comprises the following steps of S1, mouse ordering, S2, mouse immunization procedure, S3, fusion, S4, fusion detection and S5, monoclone; the monoclonal antibody for detecting the new coronavirus can effectively detect the new coronavirus, solves the problem of easy missed diagnosis in nucleic acid detection, increases IgM and IgG antibody detection when the nucleic acid detection is negative, can be used as a supplementary means for nucleic acid diagnosis, and greatly improves the accuracy of the new coronavirus detection.

Description

technical field [0001] The invention belongs to the field of biotechnology, and more specifically relates to a monoclonal antibody for detection of novel coronavirus. Background technique [0002] The detection methods of the new coronavirus mainly include nucleic acid detection, antibody detection, and antigen detection. Due to the low detection rate of antigen detection, the current detection of the new coronavirus mainly focuses on antibody and nucleic acid detection. [0003] Nucleic acid detection has high requirements for detection equipment or platforms, high-sensitivity RT-PCR instruments are expensive, and have high requirements for laboratory cleanliness and operators. In addition, nucleic acid detection takes a long time, considering sample transportation, sample In the case of a backlog, the results are usually reported within 24 hours at the fastest. Compared with nucleic acid testing, blood samples for antibody testing are easier to obtain and the quality of th...
