Background: EGFR is a transmembrane glycoprotein that is a member of the protein kinase superfamily. This protein is a receptor for members of the epidermal growth factor family. EGFR is a cell surface protein that binds to epidermal growth factor. Binding of the protein to a ligand induces receptor dimerization and tyrosine autophosphorylation and leads to cell proliferation. Activates at least 4 major downstream signaling cascades including the RAS-RAF-MEK-ERK; PI3 kinase-AKT; PLCgamma-PKC and STATs modules. May also activate the NF-kappa-B signaling cascade. Also directly phosphorylates other proteins like RGS16; activating its GTPase activity and probably coupling the EGF receptor signaling to the G protein-coupled receptor signaling.

Activity: Immobilized Human EGF(Cat: PKSH033687) at 10μg/ml(100 μl/well) can bind Human EGFR-Fc.

Sequence: Leu25-Ser645

Purity: > 95 % as determined by reducing SDS-PAGE.

Formulation: Lyophilized from a 0.2 μm filtered solution of PBS, pH7.4.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Reconstitution: Please refer to the printed manual for detailed information.

Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.

Calculated MW: 95.7 kDa

Observed MW: 130 kDa

Storage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.

Shipping: This product is provided as lyophilized powder which is shipped with ice packs.
