Anti-HSPA9 antibodies are used in the immunodetection of the protein heat shock protein family A (Hsp70) member 9. In humans, the canonical protein has a reported length of 679 amino acid residues and a mass of 73.7 kDa. Its subcellular localization is in the nucleus and mitochondria. It is notably widely expressed in many tissue types. A member of the Heat shock protein 70 protein family, HSPA9 is reported to be a chaperone protein, which plays an important role in mitochondrial iron-sulfur cluster (ISC) biogenesis. The HSPA9 gene has been associated with the disease, Anemia. Synonyms for this target antigen include CSA, EVPLS, GRP-75, GRP75, HEL-S-124m, HSPA9B, MOT, and CRP40. HSPA9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 140 citations in the literature describe the use of HSPA9 antibodies in research. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
