Antibody Type: Polyclonal

Antibody Host Species: Rabbit

Antibody Immunogen Source: Human MEKK2 (MAP3K2) sequence peptide Cat. No.: PE-04ANX90

Antibody Immunogen Sequence: RAQ(pS)YPD(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues R236 to D242; In the region between the PB1 domain and the protein kinase catalytic domain

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: MEKK2 (MAP3K2) is a protein-serine/threonine kinase of the STE group and STE11 family. It is required for cytokine production in cultured mast cells. The protein is one of the kinases that regulate different steps of the caveolar cycle. It activated by phosphorylation on T524. Methylation of the protein increases MAP kinase signalling and promotes Ras-driven carcinomas.
