EGF Antibody [Unconjugated]

Western blot shows 100 ng of Recombinant Human EGF (Catalog # 236-EG), Recombinant Mouse EGF (Catalog # 2028-EG) and Recombinant Rat EGF (Catalog # 3214-EG). PVDF Membrane was probed with 0.1 µg/mL of Goat Anti-Human EGF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF236) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for EGF at approximately 10 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3.

EGF was detected in immersion fixed paraffin-embedded sections of human placenta using Goat Anti-Human EGF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF236) at 15 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific staining was localized to syncytiotrophoblasts. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

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 Goat Anti-Human EGF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF236). The ND50 is typically 0.04-0.08 µg/mL.

Background

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 cells.

Limitations

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Primary Antibodies are guaranteed for 1 year from date of receipt.
