Active Recombinant Human CD70 protein, hFc&Avi-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : hFc&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 Human CD27 (His & hFc Tag) at 2 μg/mL (100 μL/well) can bind Human CD70 (ECD, hFc & AVI Tag), Biotinylated, the EC50 is 8-68ng/mL. | Molecular Mass : The recombinant human CD70 consists of 408 amino acids and predicts a molecular mass of 45.7 kDa. | Proteinlength : Gln39-Pro193 | Endotoxin : | Purity : > 80 % 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 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
