Principle of Assay
Chicken Luteinizing Hormone Releasing Hormone ELISA Kit (A73849) is a 2 hour competitive Enzyme-Linked Immunosorbent Assay (cELISA) designed for the in vitro quantitative determination of chicken Luteinizing Hormone Releasing Hormone in serum, plasma, tissue homogenates, and other biological fluids. A 96-well microtiter plate has been pre-coated with Luteinizing Hormone Releasing Hormone. During the assay, Luteinizing Hormone Releasing Hormone present in the standards or samples competes with immobilized Luteinizing Hormone Releasing Hormone 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 Luteinizing Hormone Releasing Hormone in the samples is inversely proportional to the OD450 value and is determined by comparison with the standard curve.
