Active Recombinant Human CD70 protein, Fc-tagged, R-PE labeled

Specification :
| Source : HEK293 | Species : Human | Tag : Fc | 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 : Measured by its binding ability in a functional ELISA. Immobilized Human CD27 His at 2 μg/ml (100 μl/well) can bind Human CD70 hFc, the EC50 of Human CD70 hFc is 15-60 ng/mL. | Molecular Mass : The recombinant human CD70/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 413 amino acids and predicts a molecular mass of 45.5 kDa. As a result of different glycosylation, the rh CD70/Fc migrates as several bands with the approximate molecular mass of 55-60, 110-120 and 160-170 kDa corresponding to the monomeric, dimeric and trimeric form respectively in SDS-PAGE under reducing conditions. | Protein Length : Gln 39-Pro 193 | 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°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.
