Product Overview
This rabbit polyclonal antibody targets pro-epidermal growth factor (gene EGF) in human samples and is validated for ELISA and Western blot. The predicted molecular weight is 134.0 kDa, and the supplier reports an observed band at about 134 kDa.
Epidermal growth factor (EGF) is a small growth factor cut from a large membrane precursor. By binding and activating EGFR, it stimulates proliferation and survival of epithelial cells, and in the kidney it promotes magnesium reabsorption. It is widely used in cell culture and studied in development and cancer.

Validated Applications
| ELISA | 0.1–0.5 µg/mL |
|---|---|
| Western blot | 0.1–0.5 µg/mL (Human) |
Samples with a confirmed band (WB): 22RV1 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.
Immunogen
Recombinant human EGF fragment (Asn971–Arg1023), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 69.8%.
Reactivity Notes
The supplier lists reactivity with human. UniProt places pro-epidermal growth factor in the membrane. Tissue expression noted by UniProt (human): Expressed in kidney, salivary gland, cerebrum and prostate. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
