Anti-SARS-CoV-2 Spike Protein (BA.5) Human IgA ELISA Kit

• Description:

  PRINCIPLE OF THE ASSAY This assay employs the quantitative indirect enzyme immunoassay technique. Recombinant SARS-CoV-2 Spike Protein (BA.5) has been pre-coated onto a microplate. Standards or samples are pipetted into the wells and any Anti-SARS-CoV-2 Spike Protein (BA.5) Human IgA present is bound by the immobilized protein. After washing away any unbound substances, a biotin-labeled Mouse Anti-Human IgA antibody is added to the wells. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of Anti-SARS-CoV-2 Spike Protein (BA.5) Human IgA bound in the initial step. The color development is stopped and the intensity of the color is measured.

• Applications:

  Used for the quantitative determination of Anti-SARS-CoV-2 Spike Protein (BA.5) Human IgA concentration in serum and plasma.

• Stability:

  When the kit was stored at the recommended temperature for 6 months, the signal intensity decreased by less than 20%.

• Shipping Conditions:

  2-8 °C

• Notes:

  For Research Use Only.
