Product Overview
This rabbit polyclonal antibody detects ribosomal RNA-processing protein 7 homolog A (gene RRP7A) in human and monkey samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 32.3 kDa, and the supplier reports an observed band at about 37 kDa.
RRP7A is a nucleolar protein involved in processing of ribosomal RNA and part of the SSU processome that assembles the small ribosomal subunit. It has also been linked to primary cilia resorption and neural progenitor proliferation, and variants have been reported in primary microcephaly.

Validated Applications
| Western blot | 0.25–0.5 µg/mL (Human, Monkey) |
|---|---|
| IHC (paraffin sections) | 2–5 µg/mL (Human) |
| Immunocytochemistry / Immunofluorescence | 5 µg/mL (Human) |
| Flow cytometry (fixed cells) | 1–3 µg/1×106 cells (Human) |
| ELISA | 0.1–0.5 µg/mL |
Samples with a confirmed band (WB): human A341 cells, human MCF-7 cells, human 293T cells, monkey COS-7 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 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:5000, ECL detection.
Samples with confirmed staining (IHC): 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): MCF-7 cells.
Samples with a confirmed signal (flow cytometry): SiHa cells.
Immunogen
Recombinant human RRP7A fragment (Met1–Asp181), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human and monkey. UniProt places ribosomal RNA-processing protein 7 homolog A in the nucleus and cell projection. Tissue expression noted by UniProt (human): Expressed in the apical radial glial cells in the developing brain. 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).
