Anti-TRO antibodies are used in the immunodetection of the protein trophinin. In humans, the canonical protein has a reported length of 1431 amino acid residues and a mass of 143.7 kDa. Up to 5 different isoforms have been reported for this protein. TRO is suspected to be involved in with bystin and tastin in a cell adhesion molecule complex that mediates an initial attachment of the blastocyst to uterine epithelial cells at the time of the embryo implantation. Synonyms for this target antigen include MAGED3, MAGE superfamily protein, MAGE-D3 antigen, magphinin, melanoma antigen, family D, 3, and MAGE-d3. TRO gene orthologs have been reported in the mouse, rat and chimpanzee species. Some Tro antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
