20 Test SARS-CoV-2 Antigen IVD Kit NASAL CE/13485 Whitelist
  Product Description
  REAGEN This kit is used for in vitro qualitative detection
  of SARS-CoV-2 antigen in human
  NASAL swab samples.
  Mechanism Of Reaction
  REAGEN This kit adopts the detection principle of double antibody sandwich method. The binding
  pad of the detection card contains colloidal gold-labeled mouse N protein monoclonal antibody I; the
  detection line (T line) of the nitrocellulose membrane is coated with mouse N protein monoclonal
  antibody II, quality control line (line C) is coated with goat anti-mouse antibody.
  The collected samples are processed by the sample extract and added. During the test, when the
  extract containing the N protein of the SARS-CoV-2 is added to the sample hole of the test card, under
  the action of chromatography, the
  sample moves to the end of the absorbent paper and first passes
  through the binding pad. The N
  protein and colloidal gold labeled mice The source N protein
  monoclonal antibody I specifically binds and continues to move to the absorbent paper end. When the
  sample moves to the T line, the N protein bound to the labeled antibody specifically binds to the N
  protein monoclonal antibody II coated in the T line in a double antibody sandwich mode, and stays at
  the T line; the remaining liquid continues to absorb water The paper end moves. When it moves to the
  C line, the mouse N protein antibody I labeled with colloidal gold specifically binds to the goat
  anti-mouse antibody in the C line. The T line shows a red band, indicating that
  the SARS-CoV-2
  antigen is positive. No matter whether the T line is colored or not, the C line should show red. If the C
  line is not colored, the test is invalid and the sample needs to be tested again.
