Anti-HSPB9 antibodies are used in the immunodetection of the protein heat shock protein family B (small) member 9. In humans, the canonical protein has a reported length of 159 amino acid residues and a mass of 17.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is reported to have testis-specific expression. It is a member of the Small heat shock protein (HSP20) protein family. Synonyms for this target antigen include cancer/testis antigen 51, heat shock protein, alpha-crystallin-related, B9, small heat shock protein B9, and heat shock protein beta-9. HSPB9 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Western Blot is a widely used application for the HSPB9 antibodies listed below. In addition, ELISA is also a common application.
