Anti-EID1 antibodies are used in the immunodetection of the protein EP300 interacting inhibitor of differentiation 1. In humans, the canonical protein has a reported length of 187 amino acid residues and a mass of 20.9 kDa. Its subcellular localization is in the nucleus and cytoplasm. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. EID1 is known to be involved with the cell cycle and cell differentiation. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include CRI1, IRO45620, PNAS-22, PTD014, RBP21, 21 kDa pRb-associated protein, CREBBP/EP300 inhibitor 1, and C15orf3. EID1 gene orthologs have been reported in the mouse, rat, bovine and chimpanzee species. Some EID1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
