Anti-TSTD1 antibodies are used in the immunodetection of the protein thiosulfate sulfurtransferase like domain containing 1. In humans, the canonical protein has a reported length of 115 amino acid residues and a mass of 12.5 kDa. Its subcellular localization is in the cytoplasm. Up to 4 different isoforms have been reported for this protein. It is reported to be highly expressed in the kidney, liver and skeletal muscle. TSTD1 is known to be involved with carbohydrate metabolism and homeostasis and the regulation of transcription. Synonyms for this target antigen include putative thiosulfate sulfurtransferase KAT, thiosulfate sulfurtransferase (rhodanese)-like domain containing 1, thiosulfate sulfurtransferase/rhodanese-like domain-containing protein 1, and thiosulfate:glutathione sulfurtransferase. TSTD1 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species. These TSTD1 antibodies are widely used in Immunohistochemistry experiments, among other applications.
