生物活性 Measure by its ability to induce TF-1 cells proliferation. The ED50 for this effect is < 5 ng/mL. The specific activity of recombinant human SCF is > 5 × 10^5 IU/mg.
纯度 > 98% as determined by SDS-PAGE. Ni-NTA chromatography.
内毒素 < 0.1 EU/μg
制剂 The protein was lyophilized from a 0.2 μm filtered solution containing 1 × PBS, pH 7.4.
复融 It is recommended to reconstitute the lyophilized protein in sterile water to a concentration not less than 100 μg/mL. Do Not Vortex! Vigorous shaking may impair the biological activity of the protein.
储存条件 Lyophilized protein should be stored at -5~-20℃ for 1 year. Upon reconstitution,store at 2-8℃ for up to 1 week. Further dilute in a buffer containing a carrier protein or stabilizer (e.g. 0.1% BSA, 10% FBS, 5% HSA or 5% trehalose solution), protein aliquots should be stored at -5~-20℃ or -80℃ for 3-6 months.
运输条件 Ambient temperature or ice pack.
有效期 12个月
背景介绍 Stem Cell Factor (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. SCF is a growth factor important for proliferation, and differentiation of hematopoietic stem cells. One of its roles is to change the BFU-E (burst-forming unit-erythroid) cells, which are the earliest erythrocyte precursors in the erythrocytic series, into the CFU-E (colony-forming unit-erythroid).
