Product Description

Principles One Step ****-Novel Coronavirus (****-nCoV) IgG/IgM Test is a colloid gold enhanced capture immunoassay for qualitative determination of ****-nCoV IgG and IgM antibody in human serum, plasma and whole blood samples. The products is pre-embedded with recombined ****-nCoV antigen and chicken IgY antibody on the nitrocellulose membrane, and coated with anti-human IgM, anti-human IgG and goat anti-chicken IgY antibody respectively on the G line, M line and C line on the nitrocellulose membrane. When a positive sample is tested, the ****-nCoV IgM and/or IgG antibody combines with the colloid gold labeled ****-nCoV antigen to form a complex. Under the action of chromatography, the complex flows along the membrane, when it passes G line and/or M line it combines with the anti-human IgM and/or IgG to forma colloid labeled chicken IgY antibody combined with goat anti-chicken IgY antibody at C line to show color. Negative samples only show color on C line.
