Anti-EN2 antibodies are used in the immunodetection of the protein engrailed homeobox 2. In humans, the canonical protein has a reported length of 333 amino acid residues and a mass of 34.2 kDa. Its subcellular localization is in the nucleus. A member of the Engrailed homeobox protein family, EN2 is known to be involved with neuronal differentiation and the regulation of apoptosis. Synonyms for this target antigen include engrailed homolog 2, engrailed-2, homeobox protein en-2, hu-En-2, and homeobox protein engrailed-2. EN2 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of EN2 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.
