Anti-LEFTY2 antibodies are used in the immunodetection of the protein left-right determination factor 2. In humans, the canonical protein has a reported length of 366 amino acid residues and a mass of 40.9 kDa. It has been described to be a secreted protein. Up to 2 different isoforms have been reported for this protein. A member of the TGF-beta protein family, LEFTY2 is known to be required for left-right (L-R) asymmetry determination of organ systems in mammals. Post-translational modifications have been described, including glycosylation. The LEFTY2 gene has been associated with the disease, Left-right axis malformations. Synonyms for this target antigen include LEFTA, LEFTYA, TGFB4, TGF-beta-4, endometrial bleeding-associated factor, and EBAF. LEFTY2 gene orthologs have been reported in the mouse and chimpanzee species. A number of LEFTY2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
