Product Overview
This rabbit polyclonal antibody recognizes small ribosomal subunit protein eS21 (gene RPS21) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA.
RPS21 (eS21) is a component of the small 40S ribosomal subunit and contributes to the ribosome's role in protein synthesis. It is studied in relation to 40S subunit maturation and translation.

Conditions in the example images (IHC): heat-mediated antigen retrieval in EDTA buffer (pH 8.0).
Immunogen
Recombinant human RPS21 fragment (Met1–Phe83), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places small ribosomal subunit protein eS21 in the cytoplasm and rough endoplasmic reticulum.
