Anti-RPL9 antibodies are used in the immunodetection of the protein ribosomal protein L9. In humans, the canonical protein has a reported length of 192 amino acid residues and a mass of 21.9 kDa. Its subcellular localization is in the cytoplasm. It is notably widely expressed in many tissue types. A member of the Universal ribosomal protein uL6 protein family, RPL9 is a known component of the large ribosomal subunit. Synonyms for this target antigen include NPC-A-16, uL6, 60S ribosomal protein L9, large ribosomal subunit protein uL6, and L9. RPL9 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of RPL9 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.
