Background
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, 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.
Description
Recombinant SCF (Kit Ligand) is a disulfide-linked monomer protein consisting of 165 amino acid residues, and due to glycosylation migrates as an approximately 23 kDa protein under non-reducing and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding murine SCF mature chain was expressed inE. coli.
UniProt
P20826
Endotoxin
< 0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Purity
≥ 95% by SDS-PAGE and HPLC
Format
Lyophilized protein
Reconstitution
Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Shipping Conditions
Gel Packs or Dry Ice
Storage Conditions
The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
Calculated Molecular Weight
23 kDa
Formulation
Lyophilized from a 0.2 µm filtered solution in 20 mM Tris, 5% trehalose, pH 7.5.
