Anti-Ribosomal Protein S9 Antibody

A polyclonal reagent from Antibodies.com recognizes Ribosomal Protein S9, a structural component of the 40S ribosomal subunit that participates in cytoplasmic protein synthesis and ribosome assembly. Raised in rabbit and supplied as an unconjugated antiserum in 100 µl volume, the antibody is validated for western blot, immunohistochemistry, immunofluorescence, and ELISA workflows on human, mouse, and rat specimens.

Ribosomal Protein S9 (RPS9) has been investigated in studies of Diamond-Blackfan anemia, a rare congenital ribosomopathy, and in cancer cell lines where altered ribosomal protein expression has been documented. Researchers apply this antibody to monitor translational machinery, probe ribosomal biogenesis, and assess housekeeping gene expression in cell lysates and tissue sections. The unconjugated format provides flexibility in choosing secondary labels and detection chemistries matched to each experimental design.
