                                    | Protein Length : | Met1-Thr394 | 
                                
                                    | 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 : | Measured by the ability of the immobilized protein to support the adhesion of NIH-3T3 mouse embryonic fibroblast cells. When 5 × 10E4 cells/well are added to mCD4-His coated plates (0.2μg/mL and 100μL/well), approximately 30% will adhere specifically after 30 minutes at 37°C. | 
                                
                                    | Molecular Mass : | The recombinant mouse CD4 consists of 379 amino acids and has a predicted molecular mass of 42.8 kDa. As a result of glycosylation, the apparent molecular mass of rmCD4 is approximately 50-55 kDa in SDS-PAGE under reducing conditions. | 
                                
                                    | Endotoxin : | < 1.0 EU per μg of the 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. |
