Anti-TRAP1 antibodies are used in the immunodetection of the protein TNF receptor associated protein 1. In humans, the canonical protein has a reported length of 704 amino acid residues and a mass of 80.1 kDa. Its subcellular localization is in the mitochondria. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Heat shock protein 90 protein family, TRAP1 is a reported chaperone that expresses an ATPase activity. Synonyms for this target antigen include HSP75, HSP90L, heat shock protein 75 kDa, mitochondrial, TNFR-associated protein 1, testicular tissue protein Li 209, and HSP 75. TRAP1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 90 citations in the literature describe the use of TRAP1 antibodies in research. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
