Product Overview
This rabbit polyclonal antibody targets heat shock protein beta-6 (gene HSPB6) in human, mouse and rat samples and is validated for ICC/IF, IHC and Western blot. The predicted molecular weight is 17.1 kDa, and the supplier reports an observed band at about 17 kDa.
HSP20 (HSPB6) is a small heat shock protein abundant in smooth, cardiac and skeletal muscle. When phosphorylated by cAMP- and cGMP-dependent kinases it promotes smooth muscle relaxation, and in the heart it has protective effects against stress, so it is studied in vascular and cardiac physiology.

Samples with a confirmed band (WB): rat cardiac muscle tissue, rat skeletal muscle tissue, rat testis tissue, mouse testis tissue, human A431 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, 50 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 1:10000, ECL detection.
Samples with confirmed staining (IHC): human skeletal muscle tissue, rat cardiac muscle tissue, human mammary cancer tissue, mouse lung tissue, mouse cardiac muscle tissue, rat lung 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 EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): A431 cells.
Immunogen
Recombinant human Hsp20 fragment (His73–Leu123), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 88.2% and 92.2%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes heat shock protein beta-6 as secreted and also located in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
