Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human MEK5 (MAP2K5, MKK5) sequence peptide Cat. No.: PE-04ANV99

Antibody Immunogen Sequence: LVN(pS)IAK(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues L308 to K314; In the protein kinase catalytic domain activation T loop region 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: MEK5 (MAP2K5) is a Dual specificity protein kinase of the STE group and STE7 family. It is activated by phosphorylation on Ser/Thr by MAP kinase kinase kinases. Activation of this pathway appear to play a critical role in protecting cells from stress-induced apopotosis, neuronal survival and cardiac development and angiogenesis by acting as a scaffold protein for the construction of a complex consisting of MAP3K2 or MAP3K3 and MAP3K5 and MAPK7.
