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: ACK1 (TNK2) is a protein-tyrosine kinase of the TK group and Ack family. It appears to be a tumour suppressor protein (TSP). Cancer-related mutations in ACK1 in human tumours point to a loss of function of the protein kinase. The active form of the protein kinase normally acts to inhibit tumour cell proliferation. It is implicated in numerous roles, including: cell spreading and migration, cell survival, cell growth, and proliferation. TNK2 is known to phosphorylate: Akt1, AR, MCF2, WASL and WWOX. In this capacity TNK2 negatively regulates the tumour suppressor, WWOX, whilst activating the oncoproteins, Akt1 and AR. Mutations in this gene have been observed in ovarian, skin, and stomach tumours. Phosphorylation at Y284 in ACK1 increases its phosphotransferase activity. Its SH3 domain appears to play an autoinhibitory role.
