Human CCL3 ELISA Kit

Human CCL3 ELISA Kit employs a two-site sandwich ELISA to quantitate CCL3 in samples. An antibody specific for CCL3 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any CCL3 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CCL3 is added to the wells. After washing, proprietary 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 CCL3 bound in the initial step. The color development is stopped and the intensity of the color is measured.
