Anti-EFNB1 antibodies are used in the immunodetection of the protein ephrin B1. In humans, the canonical protein has a reported length of 346 amino acid residues and a mass of 38 kDa. Its subcellular localization is in the cell membrane. It is widely expressed across many tissue types. A member of the Ephrin protein family, EFNB1 is known to be involved with axon guidance and cell adhesion. Post-translational modifications have been described, including glycosylation, protein cleavage and phosphorylation. The EFNB1 gene has been associated with the disease, Craniofrontonasal syndrome. Synonyms for this target antigen include CFNS, EFB1, EFL3, EPLG2, Elk-L, LERK2, ELK ligand, and CFND. EFNB1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of EFNB1 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.
