COVID-19 test kit XQX001

for antigensSARS-COV-2coronavirus

The novel coronavirus (2019-nCoV) antigen detection kit (colloidal gold method) uses immunochromatography technology and adopts the principle of double antibody sandwich method for detection. Principle： The novel coronavirus (2019-nCoV) antigen detection kit (colloidal gold method) uses immunochromatography technology and adopts the principle of double antibody sandwich method for detection. During the chromatography, the novel coronavirus (2019-nCoV) antigen in the sample reacts with the colloidal gold-labeled novel coronavirus (2019-nCoV) antibody 1 to form a complex, which moves forward along the nitrocellulose membrane under the action of chromatography. In the detection area, it combines with the novel coronavirus (2019-nCoV) antibody 2 coated on the nitrocellulose membrane to form a sandwich complex and deposits on the detection line (T line) to form a purple-red band; on the contrary, if the sample does not contain the novel coronavirus ( 2019-nCoV) antigen, the purple-red band will not form on the detection line (T line). Regardless of whether the sample contains the novel coronavirus (2019-nCoV) antigen, the chicken IgY in the gold label pad and the goat anti-chicken IgY on the detection line (C line) will form a specific binding, which forms a purple-red band at the position of the detection line (C line). Components： Composition • The packaging bag for each person contains a test card and a desiccant. • The test card is composed of a plastic shell and a test strip. • The test strip consists of a sample pad and a gold label pad (fixed with a colloidal gold-labeled novel coronavirus (2019-nCoV) antibody 1),
