ISOKine-SCF, human-NEW

Stem Cell Factor (SCF, also known as c-kit ligand, mast cell growth factor and steel factor) is a hematopoietic growth factor acting at the early stages of hematopoiesis. SCF promotes the survival, proliferation and differentiation of both myeloid and lymphoid hematopoietic progenitors in bone marrow culture. It also stimulates the growth and activation of mast cells and eosinophils. SCF has been shown to act synergistically with other growth factors, such as GM-CSF, G-CSF, IL-7 and EPO. Human SCF shows low activity on murine cells, while murine and rat SCF are fully active on human cells.

Our ISOkine™ LIF is  produced using barley grain as a bioreactor, and therefore is animal-free, serum-free and endotoxin-free. Furthermore our unique technology enables us to offer high quality human LIF at much lower prices than the market leaders.

Testimonial: Bioactivity was tested by culturing mouse ES cells either on feeders in complete medium or without feeders in a conditioned medium. In both conditions ISOkine™ LIF was added using concentrations down to 0.1 ng/ml. All concentration conditions resulted in nice looking colonies of pluripotent mouse ES cells. When the ES cells were deprived of LIF they spontaneously differentiated and were able to form embryoid bodies in hanging drops.
