Product Overview
This rabbit polyclonal antibody targets erythropoietin (gene Epo) in mouse and rat samples and is validated for Western blot. The predicted molecular weight is 21.4 kDa, and the supplier reports an observed band at about 28 kDa.
Erythropoietin (EPO) is a glycoprotein hormone made mainly by the kidney in response to low oxygen. It binds the EPO receptor on erythroid progenitors, activating JAK2-STAT5 signaling to support their survival, proliferation and differentiation into red blood cells. EPO is a central measure in studies of anemia, hypoxia and erythropoiesis.

Validated Applications
| Western blot | 0.1–0.5 µg/mL |
|---|
Samples with a confirmed band (WB): mouse small intestine tissue.
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.
Immunogen
Recombinant mouse EPO fragment (Asp34–Arg192), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with mouse and rat. UniProt describes erythropoietin as a secreted protein. Tissue expression noted by UniProt (mouse): Produced by kidney or liver of adult mammals and by liver of fetal or neonatal mammals. 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).
