Active Recombinant Human EGFR Protein, His-tagged

Specification :
| Source : CHO | Species : Human | Tag : His | Form : Lyophilized from sterile PBS, pH 7.4Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : Measured by its binding ability in a functional ELISA. Immobilized human EGED-His at 2 μg/ml (100 μl/well) can bind human Fc-EGF, the EC50 of human Fc-EGF is 30-110 ng/mL. | Molecular Mass : The recombinant human EGFR consists of 624 amino acids and predicts a molecular mass of 69.17 kDa. | Protein length : Met1-Gly640 | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE. | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°CStore it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles. | Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
