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: TAK1 (MAP3K7, MEKK7) is a protein-serine/threonine kinase of the TKL group and MLK family. TAK1 is activated by proinflammatory cytokines and in response to physical/chemical stress, including UVR, osmotic- and oxidative stress. It is a mediator of TRAF6 and TGF-beta signal transduction, and activates IKBKB and MAPK8 in response to TRAF6 signalling. It also stimulates NFκB activation and activation of the p38 MAPK (MAPK8) pathway. It is responsible for controlling a variety of cell functions such as transcription and apoptosis. It regulates hepatic cell survival and carcinogenesis. TAK1 is important for TGF-beta1 regulation of MMP9 and the metastatic potential of certain breast cancer cell lines. It is activated by phosphorylation at T178, T184, T187 and S192. It is also activated by K63-linked polyubiquitination. TAK1 plays a role in tumour initiation, progression, and metastasis such as in breast cancer as a tumour inducer or tumour suppression depending on the cancer.
