Description:
Stem Cell Factor (SCF) plays an important role in hematopoiesis and the survival, proliferation, and differentiation of mast cells, melanocytes, and germ cells. SCF mediates its biological effects by binding to and activating a receptor tyrosine kinase designated c-kit or SCF receptor (SCFR). SCF is also known as mast cell growth factor (MCGF), steel (Sl) factor (SLF), or kit ligand (KL). Recombinant mouse SCF produced in E. coli is a single, non-glycosylated polypeptide chain containing 164 amino acids and having a molecular mass of 18.3 kDa. The SCF is purified by proprietary chromatographic techniques.
