Technical Data
E3375-14
Epidermal Growth Factor Receptor (erbB, EGFR), Neutralizing
Description:
Applications:
Suitable for use in Western Blot, Immunoprecipitation, Immunohistochemistry, Immunocytochemistry and Neutralization. Other applications have not been tested.

Recommended Dilutions:
Immunohistochemistry: Acetone-fixed tissues.
Neutralization of Biological Activity: 10ug/ml causes a 74% reduction in cell number in a 5 day cell proliferation assay using A431 cells.
Western Blot: 0.5-2ug/ml detects non-reduced EGF receptor in RIPA lysates from non-stimulated human A431 cells. Non-stimulated A431 cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with E3375-14 (1ug/ml). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemilum-inescence detection system.
Immunoprecipitation: 4ug immunoprecipitates the EGF receptor from 500ug of non-stimulated A431 RIPA lysate.
Immunocytochemistry: 10ug/ml shows positive immunostaining for the EGF receptor in A431 cells fixed with 4% para-formaldehyde.
Optimal dilutions to be determined by the researcher.

Biological Activity:
Inhibits A431 cell growth. Recognizes an antigenic determinant located on the extracellular domain of the receptor.

Positive Antigen Control:
A0001-50: A431 Cells, Non-Stimulated Use 20ug per lane for minigels.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O.. Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Immunogen:
Human A431 membrane proteins.
Purity:
Purified by Protein G affinity chromatography.
Form
Supplied as a lyophilized powder from 0.1M Tris-glycine, pH 7.4, 0.15M sodium chloride. Reconstitute with 250ul sterile ddH2O. Further dilute with PBS, 5mg/ml BSA.
Specificity:
Recognizes the external domain of EGF receptor on all human cells at ~180kD. Competes with EGF and TGF-a for binding on human cells. Recognizes both phosphorylated and non-phosphorylated human EGF receptors. Species crossreactivity: does not react with EGF receptors on mouse or rat cells.
Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.
