Anti-RBFOX3 antibodies are used in the immunodetection of the protein RNA binding fox-1 homolog 3. In humans, the canonical protein has a reported length of 312 amino acid residues and a mass of 33.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is notably expressed in the hippocampus, colon, cerebral cortex, cerebellum, and caudate. RBFOX3 is known to be involved with mRNA processing and nervous system development. Synonyms for this target antigen include RNA binding protein, fox-1 homolog 3, fox-1 homolog C, hexaribonucleotide binding protein 3, neuN antigen, neuronal nuclei antigen, and RNA binding protein fox-1 homolog 3. RBFOX3 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 2100 citations in the literature describe the use of RBFOX3 antibodies in research. Immunohistochemistry is a widely used application for these antibodies. Western Blot, Immunocytochemistry, and Immunofluorescence are also common applications.
