Antibody Immunogen Sequence: KLI(pY)DFI(bA)C
Antibody Immunogen Description: Corresponds to amino acid residues K288 to I294; In the PBD 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.

Scientific Background: WASP is a member of the Wiskott-Aldrich syndrome (WAS) family of proteins. It is a cytoplasmic protein expressed exclusively in hematopoietic cells. WASP transduces signals from surface receptors to the actin cytoskeleton. It associates with the small GTPase, Cdc42, to regulate formation of actin filaments, and the cytoskeletal organizing complex, Arp2/3. It is mutated in Wiskott-Aldrich syndrome,which is a rare, inherited, X-linked, recessive disease characterized by immune dysregulation and microthrombocytopenia.
