For the quantitative determination of rat hepatocyte growth factor in serum, plasma, and tissue homogenates. Sensitivity: 0.039ng/ml Detection Range: 0.156-10ng/ml Specificity: This assay has high sensitivity and excellent specificity for detection of rat HGF. No significant cross-reactivity or interference between rat HGF and analogues was observed. Assay Principle: This assay employs the quantitative sandwich enzyme immunoassay technique. Antibody specific for HGF has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any HGF present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for HGF is added to the wells. After washing, avidin 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 HGF bound in the initial step. The color development is stopped and the intensity of the color is measured.
