Product Overview
This rabbit polyclonal antibody detects small ribosomal subunit protein eS6 (gene RPS6) in human, mouse and rat samples and is validated for IHC and Western blot. The predicted molecular weight is 28.7 kDa, and the supplier reports an observed band at about 32 kDa.
RPS6 (eS6) is a protein of the 40S ribosomal subunit best known for being phosphorylated at several C-terminal serines by S6 kinases downstream of mTORC1 and by RSK kinases downstream of ERK. Phospho-RPS6 is one of the most widely used readouts of mTOR pathway activity in cell growth and signaling studies.

Validated Applications
| IHC (paraffin sections) | 0.5–1 µg/mL (Human, Rat) |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
Samples with a confirmed band (WB): rat testis tissue, mouse testis tissue, MCF-7 cells, A549 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Samples with confirmed staining (IHC): rat brain tissue, human intestinal cancer tissue, human lung cancer tissue, rat kidney tissue.
Recommended antigen retrieval: heat-mediated, in TE buffer (pH 9.0); citrate buffer (pH 6.0) can be used instead.
Conditions in the example images (IHC): heat-mediated antigen retrieval in citrate buffer (pH 6).
Immunogen
Synthetic peptide from the N-terminal region of human RPS6. The peptide sequence is conserved in mouse and rat.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places small ribosomal subunit protein eS6 in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
