Details

The Human Hepatocyte Growth Factor (Hu HGF) ELISA quantitates Hu HGF in human serum, plasma, cell culture supernatants, or other body fluids. The assay will exclusively recognize both natural and recombinant Hu HGF. Principle of the method The Human HGF solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the binding of the second (detector) antibody to the target on a different epitope from the capture antibody. An antibody conjugated with enzyme binds the formed sandwich. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen. Rigorous validation Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.Hepatocyte growth factor (HGF) is a member of the plasminogen subfamily of S1 peptidases. The inactive polypeptide formed upon translation undergoes cleavage to produce a 69 kDa alpha-chain and 34 kDa beta-chain. A disulphide bond between the two chains makes active HGF. HGF is secreted by mesenchymal cells and stimulates mitogenesis, cell motility, and matrix invasion. It is involved in cellular growth and morphogenesis in a wide variety of tissue types. In humans, HGF is present on chromosome 7.
