Anti-RBL1 antibodies are used in the immunodetection of the protein RB transcriptional corepressor like 1. In humans, the canonical protein has a reported length of 1068 amino acid residues and a mass of 120.8 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Retinoblastoma protein (RB) protein family, RBL1 is a reported key regulator of entry into cell division. Synonyms for this target antigen include PRB1, p107, retinoblastoma-like protein 1, 107 kDa retinoblastoma-associated protein, retinoblastoma-like 1, and CP107. RBL1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RBL1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
