Abstract
The present application provides a novel coronavirus antibody detection kit based on magnetic particle chemiluminescence. The detection kit includes: streptavidin magnetic particles, biotin-labeled novel coronavirus antigens, an acridine sulfonamide-labeled secondary antibody, a sample diluent and a quality control material; wherein the biotin-labeled novel coronavirus antigens include a recombinant nucleocapsid protein and a recombinant spike protein S1. The sample to be tested, the biotin-labeled antigens and the streptavidin magnetic particles are mixed, incubated and washed, and then the acridine sulfonamide-labeled antibody is added to form a magnetic particle-streptavidin-biotin-antigen-novel coronavirus antibody-secondary antibody complex, and then the luminous intensity is detected to qualitatively determine the sample to be tested.
