Recombinant Mouse Stem Cell Factor
Stem cell factor / KIT ligand (SCF) is a cytokine which binds CD117(c-Kit). SCF is also known as steel factor" or "c-kit ligand". SCF exists in two forms
Description | Stem Cell Factor Mouse Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 165 amino acids and having a molecular mass of 18309 Dalton. The SCF is purified by proprietary chromatographic techniques. |
Protein Content | Protein quantitation was carried out by two independent methods: 1. UV spectroscopy at 280 nm using the absorbency value of 0.52 as the extinction coefficient for a 0.1% (1mg/ml) solution. This value is calculated by the PC GENE computer analysis program of protein sequences (IntelliGenetics). 2. Analysis by RP-HPLC, using a standard solution of Stem Cell Factor as a Reference Standard. |
Synonyms | Kit ligand Precursor, C-kit ligand, SCF, Mast cell growth factor, MGF, SF, KL-1, Kitl, DKFZp686F2250, Hematopoietic growth factor KL, Steel factor. |

Purity | >96% as determined by SDS-PAGE and HPLC |
Formulation | Sterile Filtered White lyophilized (freeze-dried) powder. Lyophilized from a concentrated (1mg/ml) solution in water containing 0.02% NaHCO3. |
Stability | The lyophilized form of the protein is stable at room temperature for 3 weeks and at -20°C for at least 2 years from the date of receipt. Upon reconstitution, the protein should be stored at 4°C for no more than 7 days. The protein is stable at -20°C for six months. For long term storage, please store at -80°C and the addition of a carrier protein (0.1% HSA or BSA) is recommended. Please prevent freeze-thaw cycles. |
Biological Activity | The ED50 as determined by the dose-dependant stimulation of Human TF-1 cell line is < 10 ng/ml, corresponding to a Specific Activity of 1x105 IU/mg. |
Solubility | It is recommended to reconstitute the lyophilized Stem Cell Factor in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions. |
Usage | LABORATORY RESEARCH USE ONLY. Not intended for diagnostic or therapeutic purposes. |
