< 1.0 EU per μg of the protein as determined by the LAL method
1. Measured by its binding ability in a functional ELISA. 2. Immobilized mouse EGFR-his at 10 μg/mL (100 μl/well) can bind human EGF-Fc (Cat:10605-H01H), The EC50 of human EGF-Fc (Cat:10605-H01H) is 60-90 ng/mL. 3. Immobilized mouse EGFR-his at 10 μg/mL (100 μl/well) can bind mouse EGF-Fc (Cat:50482-M01H), The EC50 of mouse EGF-Fc (Cat:50482-M01H) is 70-100 ng/mL.
A DNA sequence encoding the extracellular domain of mouse EGFR (Q01279) (Met 1-Ser 647) was fused with a polyhistidine tag at the C-terminus.
The secreted recombinant mouse EGFR comprises 634 amino acids and has a calculated molecular mass of 71 kDa. As a result of glycosylation, the apparent molecular mass of rmEGFR is approximately 100 kDa in SDS-PAGE under reducing conditions.

As a member of the epidermal growth factor receptor (EGFR) family, EGFR protein is type I transmembrane glycoprotein that binds a subset of EGF family ligands including EGF, amphiregulin, TGF-α, betacellulin, etc. EGFR protein plays a crucial role in signaling pathway in the regulation of cell proliferation, survival and differentiation. Binding of a ligand induces EGFR protein homo- or heterodimerization, the subsequent tyrosine autophosphorylation and initiates various down stream pathways (MAPK, PI3K/PKB and STAT). In addition, EGFR signaling also has been shown to exert action on carcinogenesis and disease progression, and thus EGFR protein is proposed as a target for cancer therapy currently.
