Product Overview
This rabbit polyclonal antibody targets heat shock protein beta-8 (gene HSPB8) in human, mouse and rat samples and is validated for flow cytometry, immunoprecipitation, ICC/IF, IHC and Western blot. The predicted molecular weight is 21.6 kDa, and the supplier reports an observed band at about 22 kDa.
HSPB8 (HSP22) is a small heat shock protein that works with BAG3 and HSP70 in chaperone-assisted selective autophagy, which clears damaged proteins, especially in muscle and neurons. HSPB8 mutations cause forms of inherited neuropathy and myopathy.

Immunogen
Recombinant human HSPB8/Hsp22 fragment (Met1–Thr196), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 94.4% and 95.4%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places heat shock protein beta-8 in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Predominantly expressed in skeletal muscle and heart. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
