Bio-activity Measure by its ability to induce TF-1 cells proliferation. The ED<sub>50</sub> for this effect is <5 ng/mL. The specific activity of recombinant human SCF is > 5 x 10<sup>5</sup> IU/mg.
Purity > 98 % as determined by reducing SDS-PAGE.
Endotoxin < 0.1 EU per μg of the protein as determined by the LAL method.
Storage Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃. Reconstituted protein solution can be stored at 4-8℃ for 2-7 days. Aliquots of reconstituted samples are stable at < -20℃ for 3 months.
Shipping This product is provided as lyophilized powder which is shipped with ice packs.
Formulation Lyophilized from sterile PBS, pH 7.4.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution Please refer to the printed manual for detailed information.
Background Stem Cell Factor (SCF) is a hematopoietic growth factor that exerts its activity at the early stages of hematopoiesis. SCF stimulates the proliferation of myeloid; erythroid; and lymphoid progenitors in bone marrow cultures and has been shown to act synergistically with colony stimulating factors.
