Recombinant Human CD8A protein(Met1-Asp182), His-tagged, Biotinylated

Specification :
| Source : CHO | Species : Human | Tag : C-His | Protein length : Met1-Asp182 | Form : Lyophilized from sterile PBS, pH 7.4. Normally 5 % – 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. | Molecular Mass : The recombinant human CD8a consists of 172 amino acids and predicts a molecular mass of 19 kDa. As a result of glycosylation, rh CD8a migrates as an approximately 28 kDa band in SDS-PAGE under reducing conditions. | 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.
