Summary

Intended use The product is used for the in vitro qualitative detection of
SARS-Cov-2 N-protein antigen in human nasal swab



Test principle

Latex Immunochromatography method is used to detect SARS-Cov-2 antigens. After
treatment when SARS-Cov-2 antigens in the sample are added to the detection
hole, the antigen and latex labeled antibody (monoclonal antibody against SARS-
Cov-2) form an immune complex. The complex moves with the liquid to the
nitrocellulose membrane, and the detection area of the nitrocellulose membrane
is coated with another one. When monoclonal antibody is against SARS-Cov-2
antigen, the immune complex is captured by the antibody on nitrocellulose
membrane, forming a red reaction line: the result is positive. When the sample
does not contain SARS-Cov-2 antigen or are lower than the minimum detection
limit of this kit, no red reaction line appears in the detection area: the
result is negative. At the same time, whether the result is positive or
negative, as the internal control standard of reagents, a red reaction line
will be formed in the quality control area (line C), which is used to judge
whether the chromatographic process is normal or not.



Reagents components

The reagent consists of test card, sample preservation solution , dripper and
swab. 1. The test card consists of reagent strip and plastic case. The main
components of the test strip are: Latex labeled SARS-Cov-2 nucleoprotein
monoclonal antibody; SARS-Cov-2 nucleoprotein monoclone antibody coatted in the
detection area of nitrocellulose membrane; anti mouse immunoglobulin G
polyclonal antibody fixed in the quality control area of nitrocellulose
membrane. 2. The main preservation solution was phosphate buffer (PBS, 50mm,
ph7.2).
