Recombinant Mouse Stem Cell Factor (KITLG)

SCF is a stromal cell-derived cytokine synthesized by fibroblasts and other cell types. SCF promotes proliferation and early differentiation of cells at the level of multipotential stem cells. It has been suggested that SCF is essential for optimal production of various hematopoietic lineages. The receptor for SCF, designated SCFR (CD117), is the oncogene designated as KIT. The biological activities of SCF are synergised considerably by GM-CSF and G-CSF, and also by IL7, EPO and some other growth and differentiation factors. In combination with IL7, SCF stimulates the proliferation of pre-B cells. SCF is also a potent chemoattractant for cells, such as mast cells, expressing the KIT receptor.

Storage Conditions

The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at 2° - 8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
