Anti-Tetraspanin 2 antibodies are used for the immunodetection of the protein encoded by the TSPAN2 gene. In humans, the canonical protein has a reported length of 221 amino acid residues and a mass of 24.1 kDa. Its subcellular localization is in the membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. A member of the Tetraspanin (TM4SF) protein family, it is believed to play a role in signalling in oligodendrocytes in the early stages of their terminal differentiation into myelin-forming glia and may also function in stabilizing the mature sheath. Other names for this target antigen include TSN2, new EST tetraspan 3, tetraspan 2, tetraspan NET-3, tetraspan TM4SF, and NET3. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. Some Tetraspanin 2 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
