EliKine™ Human TGF-β1 ELISA Kit

EliKine™ Human TGF-β1 ELISA Kit employs a two-site sandwich ELISA to quantitate TGF-β1 in samples. An antibody specific for TGF-β1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any TGF-β1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TGF-β1 is added to the wells. After washing, proprietary EliKine™ Streptavidin-HRP conjugates is added to the wells. Following a wash to remove any unbound streptavidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TGF-β1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
