Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human Met sequence peptide Cat. No.: PE-04AFO99

Antibody Immunogen Sequence: KE(pY)(pY)SVH(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues K1232 to H1238; In protein kinase catalytic domain activation T-loop between subdomains VII and VIII.

Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.This antibody was also subject to negative purification over phosphotyrosine-agarose.

Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: Met (HGFR) is a protein-tyrosine kinase of the TK group and Met family. It is activated by binding hepatocyte growth factor (HGF), which induces dimerization and autophosphorylation. Phosphorylation of Y1003 increases phosphotransferase activity and induces interaction with Cbl. Phosphorylation of Y1230 and Y1235 increases phosphotransferase activity. Phosphorylation of Y1234 increases phosphotransferase activity and induces interaction with Grb2. Phosphorylation of S985 inhibits phosphotransferase activity. Phosphorylation of Y1349 inhibits phosphotransferase activity, but induces interaction with FAK, Gab1, Grb2, Met, PIK3R1, PLCG1 and Src. Met mediates scattering, proliferation, survival, and morphogenesis of cells. Some immediate regulators that bind to Met after activation with HGF include PLCG1, PIK3R1, GRB2, SRC, STAT3 or the adapter GAB1. Met is a known oncoprotein (OP). Cancer-related mutations in human tumours point to a gain of function of the protein kinase. The active form of the protein kinase normally acts to promote tumour cell proliferation. Hepatocellular carcinoma (HCC) occurs with higher risk in those that have chronic HCV (hepatitis C virus) or HBV (hepatitis B virus) infection, or aflatoxin exposure in diet, or alcohol-induced cirrhosis, or another form of cirrhosis.
