The Recombinant Human SCF GMP Protein, CF from R&D Systems is derived from E. coli. The Recombinant Human SCF GMP Protein, CF has been validated for the following applications: Bioactivity.

SCF/c-kit Ligand

Proteins and Enzymes

Lyophilized from a 0.2 ╡m filtered solution in PBS with Trehalose.

Unconjugated

97%, by SDS-PAGE with quantitative densitometry by Coomassie« Blue Staining. The molecular weight by mass spectrometry is 18573 Da ▒ 50 Da

Human

18 kDa, under reducing conditions.

19 kDa

Measured in a cell proliferation assay using TF-1 human erythroleukemic cells. Kitamura, T. et al . (1989) J. Cell Physiol. 140 :323. The ED50 for this effect is 1.00-8.00 ng/mL. The specific activity of recombinant human SCF is 1.0 x 106 units/mg, which is calibrated against the human SCF reference standard (NIBSC code: 91/682).

<0.10 EU per 1 ╡g of the protein by the LAL method.
