Anti-ERO1A antibodies are used in the immunodetection of the protein endoplasmic reticulum oxidoreductase 1 alpha. In humans, the canonical protein has a reported length of 468 amino acid residues and a mass of 54.4 kDa. Its subcellular localization is in the ER, Golgi, and is secreted. It is notably expressed in many tissues, such as the cerebral cortex and cervix. A member of the EROs protein family, ERO1A is known to be involved with brown fat cell differentiation and the cellular response to hypoxia. Post-translational modifications have been described, including N-glycosylation and phosphorylation. Synonyms for this target antigen include ERO1-L-alpha, ERO1-alpha, ERO1L, ERO1LA, Ero1alpha, and ERO1-L. ERO1A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 100 citations in the literature describe the use of ERO1A antibodies in research. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
