Product Overview
This rabbit polyclonal antibody detects epidermal growth factor receptor (gene Egfr) in human and mouse samples and is validated for Western blot. The predicted molecular weight is 134.9 kDa, and the supplier reports an observed band at about 175 kDa.
Epidermal growth factor receptor (EGFR, also called ErbB1 or HER1) is a receptor tyrosine kinase activated by EGF, TGF-α and related ligands. Ligand binding triggers receptor dimerization and activation of RAS/MAPK, PI3K/AKT and other pathways that drive proliferation and survival, and EGFR is a major target in cancer research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse) |
|---|
Samples with a confirmed band (WB): human A431 cells, human A549 cells, human U87 cells, mouse liver 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, 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 mouse EGFR fragment (Leu25–Leu249), expressed in E. coli. Sequence identity with the human ortholog: 88%.
Reactivity Notes
The supplier lists reactivity with human and mouse. UniProt places epidermal growth factor receptor in the cell membrane, endoplasmic reticulum membrane, Golgi apparatus membrane and nuclear membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
