Anti-TTPA antibodies are used in the immunodetection of the protein alpha tocopherol transfer protein. In humans, the canonical protein has a reported length of 278 amino acid residues and a mass of 31.8 kDa. Its subcellular localization is in the cytoplasm. TTPA is known to bind alpha-tocopherol, enhances its transfer between separate membranes, and stimulates its release from liver cells. The TTPA gene has been associated with the disease, Ataxia with vitamin E deficiency. Synonyms for this target antigen include AVED, TTP1, alphaTTP, alpha-TTP, tocopherol (alpha) transfer protein (ataxia (Friedreich-like) with vitamin E deficiency), and ATTP. TTPA gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of TTPA antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
