Anti-CD261 antibodies enable researchers to detect and measure the CD261 antigen in biological samples. This target is a reported synonym of the TNFRSF10A gene, which encodes TNF receptor superfamily member 10a. This protein is known to function in the apoptotic pathway, among other biological roles. The human version of CD261 has a canonical amino acid length of 468 residues and a protein mass of 50.1 kilodaltons. It is reported to be localized in the cell membrane and cytoplasm of cells and notably expressed in many tissues, such as the cervix, stomach, and appendix. Other names for this target antigen include APO2 and DR4. Some CD261 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
