Anti-HSF5 antibodies are used in the immunodetection of the protein heat shock transcription factor 5. In humans, the canonical protein has a reported length of 596 amino acid residues and a mass of 65.3 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the testis. A member of the HSF protein family, HSF5 is believed to act as a transcriptional factor. Synonyms for this target antigen include heat shock factor protein 5 and heat shock transcription factor family member 5. HSF5 gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Some HSF5 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
