Product Overview
This rabbit polyclonal antibody targets heat shock protein beta-2 (gene HSPB2) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 20.2 kDa, and the supplier reports an observed band at about 22 kDa.
HSPB2 is a small heat shock protein expressed mainly in heart and skeletal muscle. It binds and may regulate myotonic dystrophy protein kinase (DMPK), and it is studied in muscle protein quality control.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Mouse, Rat, Human) |
|---|
Samples with a confirmed band (WB): rat skeletal muscle tissue, rat heart tissue, mouse C2C12 cells, mouse skeletal muscle tissue, mouse heart tissue.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 13% 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.
Immunogen
Recombinant human HSPB2 fragment (Met1–Pro182), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 97.3%.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places heat shock protein beta-2 in the cytoplasm and nucleus. Tissue expression noted by UniProt (human): Expressed preferentially in skeletal muscle and heart but not in the lens. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
