Anti-RPS3A Antibody

RPS3A (Ribosomal Protein S3A) is a core component of the 40S small ribosomal subunit and contributes to protein biosynthesis and translation initiation across eukaryotic cells. Beyond its canonical ribosomal role, the protein has been linked to DNA damage response signalling and to dysregulated growth programmes in several tumour types, making it a relevant marker for studies in cell biology, stress response, and translational oncology.

This unconjugated rabbit polyclonal reagent from Antibodies.com is supplied as a 100 µl aliquot at 1 mg/ml in PBS containing 0.1% Sodium Azide and 50% Glycerol, with the glycerol-based formulation supporting storage at standard refrigerated conditions and protecting antibody activity through repeated freeze-thaw cycles. The polyclonal format offers multi-epitope recognition of RPS3A, which can be useful when working with partially degraded lysates or with fixed tissue sections where target availability may be limited.

Validated applications include Western blot for expression profiling in cell and tissue lysates, immunohistochemistry for localisation in formalin-fixed paraffin-embedded sections, and immunofluorescence for subcellular distribution work. The reagent has been tested for reactivity against Human, Mouse, and Rat samples, enabling comparative work between established mammalian model systems and human clinical material without the need for separate species-specific reagents.
