Anti-ORW1 antibodies enable researchers to detect and measure the ORW1 antigen in biological samples. This target is a reported synonym of the ENG gene, which encodes endoglin. This protein is known to function in bone development and cell adhesion, among other biological roles. The human version of ORW1 has a canonical amino acid length of 658 residues and a protein mass of 70.6 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cell membrane of cells and notably expressed in the testis, placenta, kidney, and cerebral cortex. Other names for this target antigen include END and HHT1. A number of ORW1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Flow Cytometry, and Immunohistochemistry are also common applications.
