Anti-TTC9B antibodies are used in the immunodetection of the protein tetratricopeptide repeat domain 9B. In humans, the canonical protein has a reported length of 239 amino acid residues and a mass of 25.9 kDa. Up to 2 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the bone marrow, testis, and adrenal gland. It is a member of the TTC9 protein family. Synonyms for this target antigen include tetratricopeptide repeat protein 9B and TPR repeat protein 9B. TTC9B gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. ELISA, Western Blot, and Immunohistochemistry are common applications for TTC9B antibodies.
