Recombinant Human CTLA4 protein, His-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : His | 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. | Molecular Mass : The recombinant human CTLA4 consists of 138 amino acids and has a predicted molecular mass of 15 kDa. As a result of glycosylation, the apparent molecular mass of human CTLA4 is approximately 22-26 kDa in SDS-PAGE under reducing conditions | Protein Length : Met1-Phe162 | 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 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
