Anti-CELF2 antibodies are used in the immunodetection of the protein CUGBP Elav-like family member 2. In humans, the canonical protein has a reported length of 508 amino acid residues and a mass of 54.3 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 5 different isoforms have been reported for this protein. It is reported to be expressed in frontal cortex. A member of the CELF/BRUNOL protein family, CELF2 is known to be an RNA-binding protein implicated in the regulation of several post-transcriptional events. Synonyms for this target antigen include CUG-BP2, CUGBP2, DEE97, ETR-3, ETR3, NAPOR, CUG triplet repeat RNA-binding protein 2, and BRUNOL3. CELF2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of CELF2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
