Recombinant Human ERBB2 protein (Met1-Cys195), His-tagged

Specification :
| CommonName : ERBB2 | Source : HEK293 | Species : Human | Tag : His | Predicted N Terminal : Thr 23 | Form : Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80. | Molecular Mass : The recombinant human ERBB2 consists of 184 amino acids and predicts a molecular mass of 20.9 kDa. As a result of glycosylation, it migrates as an approximately 32 kDa protein in SDS-PAGE under reducing conditions. | Endotoxin : | Purity : > 90 % as determined by SDS-PAGE | Storage : Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store 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 0.25 mg/ml. Centrifuge the vial at 4°C before opening to recover the entire contents. | Shipping : In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
