Anti-Transketolase antibodies are used for the immunodetection of the protein encoded by the TKT gene. In humans, the canonical protein has a reported length of 623 amino acid residues and a mass of 67.9 kDa. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Transketolase protein family, it is known to catalyze the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate. Other names for this target antigen include HEL107, SDDHD, TK, TKT1, epididymis luminal protein 107, epididymis secretory protein Li 48, and HEL-S-48. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of Transketolase antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
