Anti-THSD1 antibodies are used in the immunodetection of the protein thrombospondin type 1 domain containing 1. In humans, the canonical protein has a reported length of 852 amino acid residues and a mass of 94.6 kDa. Its subcellular localization is in the endosome. Up to 3 different isoforms have been reported for this protein. It is notably expressed in soft tissue, skin, and colon. Post-translational modifications have been described, including glycosylation. The THSD1 gene has been associated with the disease, Aneurysm. Synonyms for this target antigen include 4833423O18Rik, thrombospondin, type I, domain containing 1, transmembrane molecule with thrombospondin module, and thrombospondin type-1 domain-containing protein 1. THSD1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some THSD1 antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. In addition, Immunohistochemistry is also a common application.
