Recombinant Mouse Stem Cell Factor (KITLG)

商品詳情參考文獻相關資料

	Print Version
Alternative Names	SCF, Kit ligand, c-Kit ligand, Hematopoietic growth factor KL, Mast cell growth factor, MGF, Steel factor
Description	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, mainly because of its ability to prevent apoptosis when it co-stimulates with other cytokines. The receptor for SCF, designated SCFR(CD117), is the oncogene designated as KIT. The biological activities of SCF are synergised considerably by colony stimulating factors GM-CSF and G-CSF, and also by IL-7, Epo and some other growth and differentiation factors. In combination with IL-7 SCF stimulates the proliferation of pre-B cells. SCF is also a potent chemoattractant for cells (see also: Chemotaxis), for example, mast cells, expressing the kit receptor. One response to SCF in these cells is a characteristic rearrangement of the actin filaments of the cytoskeleton.
Gene Symbol	KITLG
Gene ID	17311
Accession No.	P20826
Source	CHO cells
Appearance	Lyophilized Powder
Molecular Weight	18.0 kDa
Endotoxin Level	<1.0 EU/μg of recombinant protein as determined by the LAL method.
Purity	>95% as determined by SDS-PAGE
Bioactivity	The ED(50) was determined by the dose-dependent stimulation of the proliferation of human TF-1 cells to be < 2.0 ng/mL, corresponding to a specific activity of > 5.0 x 10^5 units/mg.
Formulation	Recombinant Stem cell factor was lyophilized from a 0.2 μm filtered solution in 20mM Tris, 5% trehalose, pH 7.5.
Reconstitution	A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.
Storage	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.
Usage	For research use only. Not for diagnostic or therapeutic use.
