Measured by its ability to neutralize EGF-induced proliferation in the Balb/3T3 mouse embryonic fibroblast cell line. The Neutralization Dose (ND50) is typically 0.05-0.1 µg/mL in the presence of 2 ng/mL Recombinant Human EGF.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
EGF in Human Skin. EGF was detected in immersion fixed paraffin-embedded sections of human skin using 25 µg/mL Mouse Anti-Human EGF Monoclonal Antibody (Catalog # MAB236) overnight at 4 °C. Tissue was stained with the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of keratinocytes in the stratum granulosum in epidermis. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
Cell Proliferation Induced by EGF and Neutralization by Human EGF Antibody. Recombinant Human EGF (Catalog # 236-EG) stimulates proliferation in the Balb/3T3 mouse embryonic fibroblast cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human EGF (2 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human EGF Monoclonal Antibody (Catalog # MAB236). The ND50 is typically 0.05‑0.1 µg/mL.

EGF is the prototypic member of a family of growth factors that are
characterized by the presence of EGF like domains and activate members
of the EGF receptor family. Proteolytic cleavage of a membrane-bound
precursor releases mature soluble EGF which interacts with the EGF R to
promote proliferation and differentiation of mesenchymal and epithelial
