Background: This Quantitative Sandwich ELISA kit is only for in vitro research use only, not for drug, household, therapeutic or diagnostic applications. It is intended to be determinated WIF1 concentrations in Rat serum, plasma and other body fluids. Using Purified Rat WIF1 antibody to coat Microelisa Stripplate wells to make solid-phase antibody, then add WIF1 and WIF1 antibody which has been labeled with HRP to wells, then the reactants become antibody-antigen-antibody-enzyme complex, after w
