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 TIG concentrations in Goat serum, plasma and other body fluids. Using Purified Goat TIG antibody to coat Microelisa Stripplate wells to make solid-phase antibody, then add TIG and TIG antibody which has been labeled with HRP to wells, then the reactants become antibody-antigen-antibody-enzyme complex, after was
