Our bioactive Stem Cell Factor (SCF) Canine, E. coli Recombinant Protein is a single, non-glycosylated polypeptide chain containing 165 amino acids and has a molecular mass of 18.4 kDa. The SCF is purified by proprietary chromatographic techniques.
Stem cell factor (SCF), also known as KIT ligand, binds to the receptor-type protein-tyrosine kinase KIT (CD117). This pleiotropic cytokine plays an essential role in the regulation of cell survival and proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration and function, and in melanogenesis. SCF exists in both a soluble and a transmembrane isoform. SCF is commonly used in cell cultures in vitro to promote expansion of primitive hematopoietic stem cells and multi-potent progenitor cells.

It is recommended to reconstitute the lyophilized Stem Cell Factor in sterile 18MΩ-cm H2O not less than 100 µg/ml, which can then be further diluted to other aqueous solutions.
At ambient temperature. Upon receipt, store the product at the temperature recommended below.
Lyophilized SCF, although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution, SCF should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.
