Anti-RPL23A antibodies are used in the immunodetection of the protein ribosomal protein L23a. In humans, the canonical protein has a reported length of 156 amino acid residues and a mass of 17.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably expressed in many tissues, such as the fallopian tube and nasopharynx. A member of the Universal ribosomal protein uL23 protein family, RPL23a is a known component of the large ribosomal subunit. Post-translational modifications have been described, including methylation. Synonyms for this target antigen include MDA20, uL23, 60S ribosomal protein L23a, large ribosomal subunit protein uL23, melanoma differentiation-associated gene 20, and L23A. RPL23A gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RPL23a antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
