Anti-ribosomal protein S3a Antibody

The Antibodies.com polyclonal reagent targets ribosomal protein S3a, a component of the 40S small ribosomal subunit that participates in translation initiation, ribosomal biogenesis, and broader ribosome-associated signaling. Raised in rabbit and supplied unconjugated, this antibody has been validated for Western blot (WB) and immunofluorescence (IF) workflows on human samples. The 100 µl volume supports multiple immunoblot and imaging experiments, while the polyclonal format enables recognition of several epitopes across the conserved RPS3a sequence for robust signal detection. Because ribosomal protein S3a is broadly expressed across human tissues and generally stable, it is frequently used as an internal loading or normalization marker alongside target proteins of interest in translation-focused studies. Investigators working on ribosome assembly, cellular stress responses, proliferative signaling, and oncogenesis pathways commonly probe RPS3a levels to evaluate translational capacity, ribosomal alterations under stress, or differential ribosome composition in disease models.
