| Full Name | | Stem Cell Factor (SCF), human |
|
| Abbreviated Name-1 | rHuSCF |
|---|
| Abbreviated Name-2 | SCF |
|---|
| Description | GenScript Stem Cell Factor (SCF), human, produced in E. coli is a single, non-glycosylated polypeptide chain containing 165 amino acids and having a molecular mass of 18,409 Da. SCF is a hematopoietic growth factor that exerts its activity during 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. |

| M.W. | 18,409 Da |
|---|
| Purity | Greater than 95.0% as determined by the following methods:
(a) Analysis by SEC-HPLC
(b) Analysis by reducing and non-reducing SDS-PAGE Silver Stained gel |
|---|
| Endotoxin Level | Less than 0.1 ng/µg (IEU/µg) of rHuSCF |
|---|
| Specific Activity | The ED50, as determined by the dose-dependant stimulation of human TF-1 cells, is < 2 ng/ml, corresponding to a specific activity of 5×105 IU/mg. |
|---|
| Storage | Although lyophilized rHuSCF remains stable at room temperature for three weeks, it is best stored desiccated below -18°C. Upon reconstitution, rHuSCF may be stored at 4°C for up to one week and below -18°C for longer periods. For long-term storage it is recommended that a carrier protein (0.1% HSA or BSA) be added. Please avoid repeated freeze-thaw cycles. |
|---|
| Formulation | Lyophilized from a concentrated (1 mg/ml) solution in water containing 10 mM Acetic acid |
|---|
| Reconstitution | It is recommended that the lyophilized rHuSCF be reconstituted in sterile 18 MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions. |
|---|
| Sequence analysis | The sequence of the first five N-terminal amino acids has been found to be Met-Glu-Gly-Ile-Cys.
