Anti-NFE2 antibodies are used in the immunodetection of the protein nuclear factor, erythroid 2. In humans, the canonical protein has a reported length of 373 amino acid residues and a mass of 41.5 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is reported to be expressed in hematopoietic cells and also in colon and testis. A member of the BZIP protein family, NFE2 is a known component of the NF-E2 complex essential for regulating erythroid and megakaryocytic maturation and differentiation. Synonyms for this target antigen include transcription factor NF-E2 45 kDa subunit, leucine zipper protein NF-E2, nuclear factor (erythroid-derived 2), 45kD, nuclear factor (erythroid-derived 2), 45kDa, and p45. NFE2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of NFE2 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.
