The Quantikine Mouse/Rat HGF Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse or rat HGF in cell culture supernates, tissue homogenates, serum, and platelet-poor plasma. It contains NS0-expressed recombinant mouse HGF and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant factor accurately. Results obtained using natural HGF showed dose-response curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural HGF.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision.
The recovery of HGF spiked into various matrices was evaluated.
Average % Recovery
Mouse Cell Culture Supernates (n=4)
Mouse Platelet-poor EDTA Plasma (n=4)
Mouse Serum (n=4)
Mouse Tissue Homogenates (n=3)
Rat Cell Culture Supernates (n=4)
Rat Platelet-poor EDTA Plasma (n=4)
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of mouse/rat HGF were serially diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
HGF (Hepatocyte Growth Factor, Scatter Factor) induces the proliferation and migration of epithelial cells, hepatocytes, chondrocytes, keratinocytes, melanocytes, endothelial cells, and many tumor cells. During organogenesis and tissue repair, HGF promotes epithelial/endothelial morphogenesis by inducing cell scattering and branching tubulogenesis. It also supports insulin production by pancreatic beta cells, neuronal survival, and immune tolerance. HGF is secreted as a propeptide that is activated by uPA or HGF Activator at sites of tissue damage. Its signaling through the receptor HGF R/c-MET is enhanced by its prior binding to heparan sulfate proteoglycans. The serum levels of HGF are elevated in a wide range of pathologies including liver damage, acute kidney failure, myocardial infarction, type 1 diabetes, obesity, and cancer, as well as in the synovial fluid of rheumatoid arthritis patients.
