Recombinant Human/Cynomolgus/Rhesus CD28 protein(Met1-Pro152), His&Avi-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human/Cynomolgus/Rhesus | Tag : C-His&Avi | Protein length : Met1-Pro152 | Conjugation/Label : Biotin | Form : Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Bio-activity : Immobilized Recombinant Mouse CD80 / B7-1 Protein (Fc Tag) at 2 μg/ml (100 μl/well) can bind Recombinant Human/Cynomolgus/Rhesus CD28 Protein(ECD,His&AVI Tag),Biotinylated, The EC50 is 800-2100 ng/mL. | Molecular Mass : The recombinant Human/Cynomolgus/Rhesus CD28 consists of 160 amino acids and predicts a molecular mass of 18.40 kDa. It migrates as an approximately 41.73 kDa band in SDS-PAGE under reducing conditions. | Endotoxin : | Purity : > 95 % as determined by SDS-PAGE. > 95 % as determined by SEC-HPLC. | 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. | Official Symbol : CD28
