Human Stem Cell Factor Recombinant (mammalian)
$160.00 – $2,700.00
accession | P21583 |
Source | Optimized DNA sequence encoding Human SCF mature chain was expressed in HEK293 Cells. |
Molecular weight | Native human Stem Cell Factor is generated by the proteolytic removal of the signal peptide and propeptide, the molecule has a calculated molecular mass of approximately 18kDa. Recombinant SCF is a protein consisting of 165 amino acid residue subunits, due to glycosylation migrates as an approximately 30kDa protein under reducing conditions in SDS-PAGE. |
Purity | >97%, as determined by SDS-PAGE and HPLC |
Biological Activity | The ED(50) was determined by the dose-dependent stimulation of the proliferation of human TF-1 cells is ≤.0 ng/ml, corresponding to a specific activity of ≥ x units/mg. |

Endotoxin | Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than.1 ng/µg(1EU/µg). |
Presentation | Recombinant SCF was lyophilized from a.2 μm filtered solution inPBSpH7.0. |
Reconstitution | A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than.1 mg/mL. This solution can then be diluted into other buffers. |
Storage | The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at° -° 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 | This cytokine product is for research purposes only.It may not be used for therapeutics or diagnostic purposes. |
