Mouse Stem Cell Factor Recombinant Protein #80428
Product Information
Storage
Mouse Stem Cell Factor Recombinant Protein is supplied as lyophilized material that is very stable at -20ºC. It is recommended to reconstitute with sterile water at a concentration of 0.1 mg/mL which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long-term storage.
Once in solution, store at 4ºC and use within 1 month, or store at -20ºC to -80ºC and use within 3 months to prevent loss of potency. Aliquot to avoid mutiple freeze/thaw cycles if storing reconstituted material at -20ºC to -80ºC.

Background
Stem cell factor (SCF) is a growth factor that is essential for hematopoiesis, melanogenesis and fertility. SCF is also known as mast cell growth factor (MCGF), steel factor (SLF), or kit ligand (KL) (1-3). SCF mediates its biological effects by binding to and activating c-Kit (4). SCF induces dimerization of c-Kit followed by trans-autophosphorylation of the cytoplasmic protein tyrosine kinase domain, leading to subsequent recruitment of signaling proteins, tyrosine phosphorylation of substrates, and activation of multiple signaling pathways (5,6). SCF/c-Kit may take part in the growth control of human malignancies (7).
