Stem Cell Factor (SCF) is a critical factor in the maintenance and expansion of hematopoietic stem cells (HSCs) in the bone marrow microenvironment. Key myeloid progenitor differentiation factor for a variety of myeloid cells such as megakaryocytes, basophils, neutrophils, and monocytes, Stem Cell Factor is also a primary growth and activation factor for mast cells and eosinophils.

Recombinant SCF is a highly pure 18.5 kDa monomer, animal origin-free (AOF) and carrier-protein-free (CF). Qkine has optimised the SCF manufacture process to produce a highly bioactive protein with excellent lot-to-lot consistency for enhanced experimental reproducibility.
