MilliTrace Rodent Neural Stem Cell Basal Medium is a defined serum-free, growth factor-free medium that has been optimized for the growth and in vitro differentiation of MilliTrace GFP reporter neural stem cells derived from rodents. When used in conjunction with puromycin (provided) and FGF or FGF, EGF and heparin (not provided), the basal medium will allow for the proliferation of MilliTrace GFP reporter rat and mouse neural stem cells, respectively. Removal of the growth factors from the Neural Stem Cell Basal Medium will result in the spontaneous differentiation of MilliTrace GFP reporter rodent neural stem cells. Puromycin Solution is provided to maintain the expression of the transgene.
