| Protein Length : |
1-203 a.a. |
| Form : |
Lyophilized from sterile PBS, pH 7.4Please 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 its ability to inhibit the proliferation of M1 mouse myeloid leukemia cells.The ED50 for this effect is typically 0.1-0.5 ng/ml. |
| Molecular Mass : |
The secreted recombinant mouse LIF comprises 191 amino acids and has a calculated molecular mass of 21.3 kDa. As a result of glycosylation, the apparent molecular mass of the monomer is approximately 35-45 kDa in SDS-PAGE under reducing conditions. |
| Proteinlength : |
Met1-Phe203 |
| Endotoxin : |
< 1.0 EU per μg of the protein as determined by the LAL method |
| Purity : |
> 85 % 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. |
