产品详细信息
Human SCF 300-07
别名:
Stem Cell Factor, c-Kit Ligand, Mast Cell Growth Factor (MGF), Steel Factor
描述:
Stem
Cell Factor (SCF) is a hematopoietic growth factor that exerts its
activity by signaling through the c-Kit receptor. SCF and c-Kit are
essential for the survival, proliferation and differentiation of
hematopoietic cells committed to the melanocyte and germ cell lineages.
Human SCF manifests low activity on murine cells, while murine and rat
SCF are fully active on human cells. Recombinant human SCF is an 18.4
kDa polypeptide containing 165 amino acid residues, which corresponds to
the sequence of the secreted soluble form of SCF.
