The Recombinant Human FGF-18 Protein is derived from E. coli. The Recombinant Human FGF-18 Protein has been validated for the following applications: Bioactivity.


E. coli-derived Glu28-Ala207, with a N-terminal Met
>95%, by SDS-PAGE visualized with Silver Staining and quantitative densitometry by Coomassie™ Blue Staining
E. coli-derived human FGF-18 protein Glu28-Ala207,with a N-terminal Met
<0.10 EU per 1μg of the protein by the LAL method.
Measured in a cell proliferation assay using BaF3 mouse pro-B cells transfected with human FGF RIIIc. The ED50 for this effect is typically 4-24ng/mL
Lyophilized from a 0.2 μm filtered solution in MOPS, Na 2 SO 4 EDTA and Trehalose.
Observed M.W.: 19-24kDa, reducing conditions, Theoretical M.W.: 21kDa
