This product is used for the in vitro qualitative detection of new coronavirus (2019-nCoV) IgM/IgG antibodies in human serum, plasma and venous whole blood samples. It uses immunochromatography technology and adopts the principle of indirect method for detection. During the chromatography, the new coronavirus (2019-nCoV) IgM/IgG antibody in the sample reacts with the colloidal gold-labeled new coronavirus (2019-nCoV) antigen to form a complex, which moves forward along the nitrocellulose membrane under the action of chromatography Moving to the detection area, it is captured by the anti-human IgM/IgG coated on the nitrocellulose membrane and forms a complex that deposits in the G and M areas to form a purple-red detection line; on the contrary, the sample does not contain the new coronavirus (2019-nCoV) IgM/IgG antibodies will not form visible purple-red lines in the G and M areas. Regardless of whether the sample contains the new coronavirus (2019-nCoV) IgM/IgG antibody, the rabbit IgG in the gold label pad and the detection line (C line) goat anti-rabbit IgG will form a specific binding, at the detection line (C line) position A purple-red line is formed.
