Anti-RBPJL antibodies are used in the immunodetection of the protein recombination signal binding protein for immunoglobulin kappa J region like. In humans, the canonical protein has a reported length of 517 amino acid residues and a mass of 56.8 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the pancreas. A member of the Su(H) protein family, RBPJL is known to be involved with signal transduction pathways. Synonyms for this target antigen include RBPSUHL, SUHL, recombining binding protein suppressor of hairless-like protein, transcription factor RBP-L, and RBPL. RBPJL gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Some RBPJL 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.
