This Human Protein Wnt-7a (WNT7A) ELISA Kit employs a two-site sandwich ELISA to quantitate WNT7A in samples. An antibody specific for WNT7A has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyWNT7A present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for WNT7A 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 WNT7A bound in the initial step. The color development is stopped and the intensity of the color is measured.
