Anti-C9orf97 antibodies enable researchers to detect and measure the C9orf97 antigen in biological samples. This target is a reported synonym of the TSTD2 gene, which encodes thiosulfate sulfurtransferase like domain containing 2. The human version of C9orf97 has a canonical amino acid length of 516 residues and a protein mass of 58.3 kilodaltons, although 2 isoforms have been identified.
