Product Overview
Clone ICB-8 is a rabbit monoclonal antibody that recognizes heat shock-related 70 kDa protein 2 (gene HSPA2) in human, mouse and rat samples and is validated for Western blot and IHC. The predicted molecular weight is 70.0 kDa, and the supplier reports an observed band at about 70 kDa.
HSPA2 is a testis-enriched HSP70 chaperone that is required for meiosis during spermatogenesis in mice. It helps assemble and stabilize protein complexes in developing sperm, and it is studied in male fertility and in some tumors that express it.

Validated Applications
| Western blot | 1:500–1:2000 |
|---|---|
| Immunohistochemistry | 1:50–1:200 |
Samples with a confirmed band (WB): human MCF-7 cells, human HepG2 cells, human HeLa cells, human A431 cells, rat testis tissue, rat C6 cells, mouse testis tissue, mouse NIH/3T3 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 10% SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:1000 overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human HSPA2.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places heat shock-related 70 kDa protein 2 in the cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
