General description

Heat shock proteins 90 (HSP90) subunits α and β, also known as HSP90AA1 and HSP90AB1 respectively, belong to the heat shock proteins (HSPC) family of highly conserved chaperones proteins, which are classified according to their cellular localization and their expression pattern. These stress inducible proteins, which includes Hsp20, Hsp60, Hsp70, and Hsp90 are molecular chaperones that bind other proteins assisting their correct folding. Hsp90 is dispensable in bacteria but is essential, conserved and highly abundant in eukaryotes, even under nonstress conditions.

Specificity

Anti-HSP90 antibody specifically recognizes human, mouse and rat HSP90.

Immunogen

Synthetic peptide corresponding to the C-terminal region of human HSP90, conjugated to KLH

Application

Anti-HSP90 antibody produced in rabbit has been used in various immunochemical techniques including immunoblotting (~90 kDa). Detection of the HSP90 band by Immunoblotting is specifically inhibited by the immunogen.

Biochem/physiol Actions

The heat shock proteins 90 (Hsp90) proteins facilitates various essential physiological processes such as cell survival, cell cycle control, hormone signaling, and apoptosis. Upregulated expression of Hsp90 is associated with the development of various pathological conditions, including several types of cancer, viral infection, inflammation, and neurodegenerative diseases.

Physical form

Solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative.

Storage and Stability

For continuous use, store at 2-8°C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
