Product Overview
This rabbit polyclonal antibody detects small ribosomal subunit protein uS8 (gene RPS15A) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 14.8 kDa, and the supplier reports an observed band at about 15 kDa.
RPS15A (uS8) is a component of the small 40S ribosomal subunit and of the nucleolar SSU processome that builds it. It is needed for normal ribosome production, and its role in red blood cell formation is supported by reports of RPS15A variants in Diamond–Blackfan anemia.

| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human HepG2 cells, human THP-1 cells, human 293T cells, rat RH35 cells, mouse NIH/3T3 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, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.25 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): human colon adenocarcinoma tissue, human placenta tissue, human testicular seminoma 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 EDTA buffer (pH 8.0).
Samples with confirmed staining (ICC/IF): HeLa cells.
Samples with confirmed staining (ICC/IF): human testis cancer tissue.
Samples with a confirmed signal (flow cytometry): HL-60 cells.
Immunogen
Recombinant human RPS15A fragment (Met1–His113), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places small ribosomal subunit protein uS8 in the cytoplasm and nucleus. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
