Introduction:
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).
