Anti-TKTL2 antibodies are used in the immunodetection of the protein transketolase like 2. In humans, the canonical protein has a reported length of 626 amino acid residues and a mass of 67.9 kDa. It is notably expressed in hepatoma cancer cells. A member of the Transketolase protein family, Tktl2 is known to play an important role in total transketolase activity and cell proliferation in cancer cells; after transfection with anti-TKTL1 siRNA, total transketolase activity dramatically decreases and proliferation was significantly inhibited in cancer cells. Synonyms for this target antigen include transketolase-like protein 2 and testis tissue sperm-binding protein Li 39a. TKTL2 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some Tktl2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
