Anti-Complexin 2 antibodies are used for the immunodetection of the protein encoded by the CPLX2 gene. In humans, the canonical protein has a reported length of 134 amino acid residues and a mass of 15.4 kDa. Its subcellular localization is in the nucleus and cytoplasm. A member of the Complexin/synaphin protein family, it is reported to negatively regulate the formation of synaptic vesicle clustering at active zone to the presynaptic membrane in postmitotic neurons. Other names for this target antigen include CPX-2, CPX2, Hfb1, CPX II, complexin II, synaphin 1, and 921-L. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of Complexin 2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunocytochemistry, and Immunofluorescence are also common applications.
