Description
Description: This Human Progesterone receptor (PGR) ELISA Kit employs a two-site sandwich ELISA to quantitate PGR in samples. An antibody specific for PGR has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any PGR present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PGR is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PGR bound in the initial step. The color development is stopped and the intensity of the color is measured.
