Antibody Immunogen Source: Human HSP90AB1 (HSP90B; HSP90-beta) sequence peptide Cat. No.: PE-04AFE99

Antibody Immunogen Sequence: KSI(pY)YIT(bA)C

Antibody Immunogen Description: Corresponds to amino acid residues K481 to T487; In the middle of the HSP90 domain. This is the major in vivo phosphorylation site in HSP90AB1.

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: HSP90-beta is a molecular chaperone that promotes the maturation, structural maintenance and proper regulation of specific target proteins involved in diverse cellular functions such as cycle control. It induces conformational changes in the client proteins in an ATP-dependent process as an ATPase, and causes their activation. Interacts dynamically with various co-chaperones that modulate its substrate recognition, ATPase cycle and chaperone function.
