| 生物活性 |
Measure by its ability to induce TF-1 cells proliferation. The ED50 for this effect is <5 ng/mL. The specific activity of recombinant human SCF is > 5 x 105 IU/mg.
|
| 纯度 |
> 98 % as determined by reducing SDS-PAGE.
|
| 内毒素 |
< 0.1 EU per μg of the protein as determined by the LAL method.
|
| 保存条件 |
Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.
|
| 运输条件 |
This product is provided as lyophilized powder which is shipped with ice packs.
|
| 制剂 |
Lyophilized from sterile PBS, pH 7.4.
Normally 5% - 8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the printed manual. |
| 复溶方法 |
Please refer to the printed manual for detailed information.

| 背景 |
Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. SCF stimulates the proliferation of myeloid; erythroid; and lymphoid progenitors in bone marrow cultures and has been shown to act synergistically with colony stimulating factors.
