1. A novel coronavirus antibody detection kit based on magnetic particle chemiluminescence, comprising:
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;
wherein, in the recombinant nucleocapsid protein, oligoproline residues are used to connect dominant epitopes of an original nucleocapsid protein, and oligolysine residues are used to form a C-terminus;
in the recombinant spike protein S1, oligoproline residues are used to connect dominant epitopes of an original spike protein S1, and oligolysine residues are used to form a C-terminus;
the recombinant nucleocapsid protein includes the amino acid sequence as shown in SEQ ID NO: 1; and
the recombinant spike protein S1 includes the amino acid sequence as shown in SEQ ID NO: 3.
