Anti-HSP90AB1 (phospho S254) Antibody

From Antibodies.com, this rabbit polyclonal IgG reagent recognizes HSP90AB1 (also known as HSP90β) only when phosphorylated at serine 254. The unconjugated antibody is supplied in a 200 µl vial and is validated for Western blot applications across human, mouse and rat samples.

HSP90β is the stress-responsive β isoform of the 90 kDa heat shock protein chaperone family, where it assists folding and stabilization of client proteins including kinases, transcription factors and steroid hormone receptors. Detection of the phospho-S254 modification allows researchers to monitor chaperone activation states and post-translational regulation linked to cellular stress, kinase signalling, and proteostasis pathways.
