Problems solved by technology

The disadvantage of this method is that the lateral flow chromatography method uses one type of at most two types of proteins for detection, and there is no cleaning process. Since the blood of individual patients contains rheumatoid factors, heterophilic antibodies, autoantibodies, and drugs and tumor cel

Abstract

The invention relates to a novel coronavirus 2019-nCoV antibody spectrum detection kit, and belongs to the technical field of novel coronavirus 2019-nCoV detection. The detection kit provided by the invention comprises a barreled test strip, a bottled sample diluent, a bottled eluent, a bottled detection antibody, a bottled substrate A, a bottled substrate B, an incubation tank, tweezers, an instruction book and a self-sealing bag. According to the detection kit provided by the invention, the antibodies (IgM/IgG/IgA/IgE) in a serum or plasma sample are jointly detected by utilizing various novel coronavirus specific recombinant antigen test strips; the kit can be used for in-vitro qualitative detection of novel coronavirus antibodies in human serum or plasma samples, effectively increasessensitivity and specificity, timely finds early infected people, can be used for disease course monitoring of evaluation and diagnosis of antibodies in rehabilitation patients, and can be widely usedfor evaluation of vaccine human body effects in the future.

Description

technical field [0001] The invention relates to a novel coronavirus 2019-nCoV antibody spectrum detection kit, which belongs to the technical field of novel coronavirus 2019-nCoV detection. Background technique [0002] Western blotting is a hybridization technique that combines high-resolution gel electrophoresis and immunochemical analysis techniques. Western blotting has the advantages of large analysis capacity, high sensitivity, and strong specificity. It is the most commonly used method for detecting protein characteristics, expression, and distribution. It is used for qualitative and quantitative detection of tissue antigens, mass determination of polypeptide molecules, and virus detection. Antibody or antigen detection, etc. [0003] Traditional western blotting is performed in three stages. The first stage is SDS-polyacrylamide gel electrophoresis (SDS-PAGE): protein samples such as antigens are negatively charged after SDS treatment, and migrate from the cathode ...
