Anti-CTCFL antibodies are used in the immunodetection of the protein CCCTC-binding factor like. In humans, the canonical protein has a reported length of 663 amino acid residues and a mass of 75.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 11 different isoforms have been reported for this protein. It is reported to have testis-specific expression. A member of the CTCF zinc-finger protein family, CTCFL is known to be involved with the cell cycle and the regulation of transcription. Synonyms for this target antigen include BORIS-like protein, brother of the regulator of imprinted sites, cancer/testis antigen 27, and transcriptional repressor CTCFL. CTCFL gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. A number of CTCFL 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.
