Product Overview
This rabbit polyclonal antibody detects heat shock protein HSP 90-beta (gene HSP90AB1) in human, mouse and rat samples and is validated for ICC/IF, IHC and Western blot. The predicted molecular weight is 83.3 kDa, and the supplier reports an observed band at about 90 kDa.
HSP90β (HSP90AB1) is the constitutively expressed form of the HSP90 chaperone. It uses ATP-dependent conformational cycles and co-chaperones to support folding, stability and activity of many client proteins, including kinases and steroid hormone receptors, and it is studied in protein homeostasis, signaling and cancer.

Samples with a confirmed band (WB): human A549 cells, human HeLa cells, human Jurkat cells, human K562 cells, human HEK293 cells, rat PC-12 cells, mouse NIH/3T3 cells, mouse ANA-1 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): mouse testis tissue, rat intestine tissue, human placenta tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Samples with confirmed staining (ICC/IF): A431 cells.
Samples with confirmed staining (ICC/IF): human lung cancer tissue, mouse brain tissue.
Immunogen
Synthetic peptide from the C-terminal region of human hsp90 beta. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes heat shock protein HSP 90-beta as secreted and also located in the cytoplasm, melanosome and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
