Human EGF Antibody

(6 citations)   
  • Species Reactivity
    Human
  • Specificity
    Detects human EGF in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant rat EGF is observed, 10% cross-reactivity with recombinant mouse EGF, and less than 1% cross-reactivity with recombinant human (rh) AR, rhBTC, rhHB-EGF, rhHRG-alpha, or rhHRG1-beta 1 is observed.

  • Immunohistochemistry
    5-15 µg/mL
    See below
  • Neutralization
    Measured by its ability to neutralize EGF-induced proliferation in the Balb/3T3 mouse embryonic fibroblast cell line. The Neutralization Dose (ND50) is typically 0.04-0.08 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.
Data Examples
Detection of Recombinant Human, Mouse, and Rat EGF by Western Blot. 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.
Immunohistochemistry
EGF in Human Placenta. 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.
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 Goat Anti-Human EGF Antigen Affinity-purified Polyclonal Antibody (Catalog # AF236). The ND50 is typically 0.04-0.08 µg/mL.

Background: EGF
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.
