Anti-EPDR1 antibodies are used in the immunodetection of the protein ependymin related 1. In humans, the canonical protein has a reported length of 224 amino acid residues and a mass of 25.4 kDa. Its subcellular localization is in the lysosomes and is secreted. Up to 3 different isoforms have been reported for this protein. It is ubiquitously expressed across many tissue types. A member of the Ependymin protein family, EPDR1 is known to bind anionic lipids and gangliosides at acidic pH. Post-translational modifications have been described, including N-glycosylation. Synonyms for this target antigen include MERP-1, MERP1, UCC1, mammalian ependymin-related protein 1, ependymin related protein 1, and EPDR. EPDR1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some EPDR1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
