Protein UniProt: Q12866

Protein SigNET: Q12866

Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human MERTK (MER) sequence peptide Cat. No.: PE-04ANY99

Antibody Immunogen Sequence: KKI(pY)SGD(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues K746 to D752; 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.

Antibody Positive Control: The observed molecular mass of the processed target protein on SDS-PAGE gels is reported to be around 105-115 kDa.
Scientific Background: MERTK (MER) is a protein-tyrosine kinase of the TK group and Axl family. It is a receptor kinase that functions in the regulation of cell survival, angiogenesis, migration and invasion, differentiation, and phagocytosis of apoptotic cells. Phosphorylation of Y749, Y753 and Y754 increases phosphotransferase activity.
