Bovine IgA (Immunoglobulin A) ELISA Kit
Bovine IgA (Immunoglobulin A) ELISA Kit
The Bovine IgA (Immunoglobulin A) ELISA Kit measures IgA in Bovine Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with IgA. IgA in the sample or standard competes with a fixed amount of biotin-labeled IgA for sites on a pre-coated antibody specific to IgA. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. Add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of IgA in the sample. The concentration of the target substance is inversely proportional to the OD450 value.
