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 : |
Measured by the ability of the immobilized protein to support the adhesion of NIH-3T3 mouse embryonic fibroblast cells.When 5×10^4 cells/well are added to CD4-Fc-coated plates (1.25μg/mL, 100 μL/well),approximately 20%-50% cells will adhere after 30 minutes at 37℃. |
Molecular Mass : |
The recombinant human CD4 consists of 603 amino acids and predicts a molecular mass of 67.4 kDa. |
Endotoxin : |
< 1.0 EU per μg protein as determined by the LAL method. |
Purity : |
> 95 % 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. |
