Principle of Assay
Universal 13,14 Dihydro-15-keto Prostaglandin F2 alpha (PGFM) ELISA Kit (A326823) is a 2 hour competitive Enzyme-Linked Immunosorbent Assay (cELISA) designed for the in vitro quantitative determination of universal 13,14 Dihydro-15-keto Prostaglandin F2 alpha (PGFM) in serum, plasma, cell culture supernatant, cell or tissue lysate, and other biological fluids. A 96-well microtiter plate has been pre-coated with 13,14 Dihydro-15-keto Prostaglandin F2 alpha (PGFM). During the assay, 13,14 Dihydro-15-keto Prostaglandin F2 alpha (PGFM) present in the standards or samples competes with immobilized 13,14 Dihydro-15-keto Prostaglandin F2 alpha (PGFM) for binding to an assay-specific antibody. Following incubation, unbound components are removed by washing and HRP-Streptavidin conjugate is added to the wells. After further incubation and washing, TMB substrate solution is added to visualize the HRP enzymatic reaction. This produces a blue-coloured product that changes to yellow following addition of acidic stop solution. The intensity of the colour is measured at 450 nm using a microplate reader. The concentration of 13,14 Dihydro-15-keto Prostaglandin F2 alpha (PGFM) in the samples is inversely proportional to the OD450 value and is determined by comparison with the standard curve.
