Human PI (Proinsulin) ELISA Kit
Human PI (Proinsulin) ELISA Kit
This Proinsulin ELISA kit is based on Sandwich ELISA detection method and takes approximately 4 hours. The microplate provided in this kit has been precoated with anti PI antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with PI bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again 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 PI in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.
