Active Recombinant Human ERBB2 Protein, His-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : His | Form : Lyophilized from sterile 50 mM Tris, pH 8.0.Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : Immobilized Her2/ERBB2 Protein, Human, Recombinant (ECD, His Tag), Biotinylated at 2 μg/ml (100 μl/well) can bind Anti-Erbb2 Antibody (Trastuzumab), the EC50 is 25-150 ng/mL. | Molecular Mass : The recombinant human ERBB2 consists of 153 amino acids and predicts a molecular mass of 17.1 kDa. | Protein Length : Pro489-Cys630 | Endotoxin : | Purity : > 85 % 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℃ before opening to recover the entire contents.
