Product Overview
This rabbit polyclonal antibody detects heat shock protein HSP 90-alpha (gene HSP90AA1) in human, monkey, mouse and rat samples and is validated for flow cytometry, ICC/IF, IHC and Western blot. The predicted molecular weight is 84.7 kDa, and the supplier reports an observed band at about 90 kDa.
HSP90α (HSP90AA1) is the stress-inducible form of the HSP90 molecular chaperone. It works through an ATP-driven cycle with many co-chaperones to fold, stabilize and activate client proteins such as kinases, steroid receptors and transcription factors. Because many cancer-related proteins depend on it, HSP90 is a major research and drug target.

Samples with confirmed staining (ICC/IF): U2OS cells.
Samples with a confirmed signal (flow cytometry): SiHa cells.
Immunogen
Synthetic peptide from the C-terminal region of human hsp90 alpha. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, monkey, mouse and rat. UniProt places heat shock protein HSP 90-alpha in the nucleus, cytoplasm, melanosome and cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
