Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate SERPINB9 in samples. An antibody specific for SERPINB9 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anySERPINB9 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for SERPINB9 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 SERPINB9 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:PI9 belongs to the large superfamily of serine proteinase inhibitors (serpins), which bind to and inactivate serine proteinases. These interactions are involved in many cellular processes, including coagulation, fibrinolysis, complement fixation, matrix remodeling, and apoptosis.
Serpins are a group of proteins with similar structures that were first identified as a set of proteins able to inhibit proteases. The acronym serpin was originally coined because many serpins inhibit chymotrypsin-like serine proteases (serine protease inhibitors).
