The 2019-nCoV Neutralization Antibody Test Kit adopted Colloidal Gold Immunochromatography for measuring functional neutralizing antibodies to COVID-19. It is a rapid COVID-19 Neutralizing Antibody Test.
Immunocolloidal gold technique is a kind of technique that uses colloidal gold as a marker. This kind of special metal particle is hydrosol form of gold and it can bind proteins rapidly and stably. Moreover, colloidal gold has little effect on biological activity of natural proteins.
Used for qualitative detection of neutralizing antibodies to 2019-nCoV in clinical samples (serum/plasma/ whole blood).
The test kit contains colloidal gold labeled 2019-nCoV Spike Protein (RBD), mouse-anti human IgG antibody immobilized in G test area, mouse-anti human IgM antibody immobilized in M test area.
