< 1.0 EU per μg of the protein as determined by the LAL method
Measured by its binding ability in a functional ELISA. Immobilized canine EGFR-His at 10 μg/ml (100 μl/well) can bind biotinylated canine His-EGF(Cat:70013-D07E), The EC50 of biotinylated canine His-EGF(Cat:70013-D07E) is 0.16-0.36μg/ml
A DNA sequence encoding the canine EGFR (XP_533073.3) (Met1-Ser618) was expressed with a C-terminal polyhistidine tag.
The recombinant canine EGFR comprises 629 amino acids and has a predicted molecular mass of 69.8 kDa. The apparent molecular mass of the protein is approximately 87.2 kDa in SDS-PAGE under reducing conditions.
Lyophilized from sterile 20 mM Tris, 500 mM NaCl, 10 % glycerol, pH 7.0. 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. 2. Please contact us for any concerns or special requirements.

EGFR Protein, Canine, Recombinant (His Tag): 图片
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.
