This Human Phosphotylinosital 3 kinase (PI3K) ELISA Kit employs a two-site sandwich ELISA to quantitate PI3K in samples. An antibody specific for PI3K has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPI3K present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PI3K 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 PI3K bound in the initial step. The color development is stopped and the intensity of the color is measured.
