Rabbit SIGA (Secretory Immunoglobulin A) ELISA Kit
Rabbit SIGA (Secretory Immunoglobulin A) ELISA Kit
The Rabbit SIGA (Secretory Immunoglobulin A) ELISA Kit measures sIgA in Rabbit Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Double antibody-Sandwich ELISA detection method and takes 3h assay time. The microplate provided in this kit has been precoated with anti sIgA antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add HRP-detection antibody, then it binds with sIgA bound to precoated antibody. Wash unbound components and 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. Calculate the concentration of sIgA in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.
