Active Recombinant Human ERBB2 protein, His&Avi-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : His&Avi | Form : Lyophilized from sterile PBS, pH 7.4.Please contact us for any concerns or special requirements. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA. | Bio-activity : Immobilized Anti-Erbb2 Antibody (Trastuzumab)at 2μg/mL (100μL/well) can bind Recombinant Human HER2 / ErbB2 Protein (His & AVI Tag), Biotinylated, the EC50 is 1.25-3.75 ng/mL. | Molecular Mass : The recombinant human ERBB2 consists of 656 amino acids and predicts a molecular mass of 72.62 kDa. It migrates as an approximately 95.91 kDa band in SDS-PAGE under reducing conditions. | Proteinlength : Met1-Thr652 | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE. > 90 % as determined by SEC-HPLC. | 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.
