Anti-RPS6 antibodies are used in the immunodetection of the protein ribosomal protein S6. In humans, the canonical protein has a reported length of 249 amino acid residues and a mass of 28.7 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is notably widely expressed in many tissue types. A member of the Eukaryotic ribosomal protein eS6 protein family, RPS6 is a known component of the 40S small ribosomal subunit. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include eS6, 40S ribosomal protein S6, phosphoprotein NP33, small ribosomal subunit protein eS6, and S6. RPS6 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Over 9700 citations in the literature describe the use of RPS6 antibodies in research. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
