COVID-19 Neutralizing Antibody Test Kit (Colloidal Gold) is a solid phase immunochromatographic assay for the rapid ,qualitative detection of Neutralizing Antibody of COVID-19 in human whole blood/se-rum/plasma. This test provides only a preliminary test result. PACK FORMATS 1 test/box, 20 tests/box,50 tests/box，100 tests/box INTRODUCTION The novel coronaviruses belong to the β genus.COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Infection with COVID-19 initiates an immune response, which includes the production of antibodies in the blood. The secreted antibodies provide protection against future viral infections, because they will stay inthe circulatory system from months to years after infection, and will quickly and strongly bind to thepathogen to block cellular infiltration and replication. These antibodies are named neutralizing antibodies. PRINCIPLE The COVID-19 Neutralizing Antibody Test kit (Colloidal Gold) is a colloidal gold immunochromatographic assay. Using the gene sequence of the COVID-19 virus surface spike protein S1 subunit (receptor binding domain, RBD), a RBD protein was produced; this RBD protein was labeled with colloidal gold, and the area of the detection line T of the nitrocellulose membrane was coated with a sufficient amount of Mouse anti-human polyclonal antibody, the new coronavirus neutralizing antibody will bind to the RBD protein and form a complex of RBD protein-neutralizing antibody-mouse anti-human polyclonal antibody in the area of the detection line T, making a purple-red line on the detection line T.
