Source:Recombinant corresponding to 195aa from human Fibroblast Growth Factor 17 expressed in E. coli.
Molecular Weight:~22.7kD
Endotoxin: ~0.1ng/ug
Biological Activity:ED50 <0.5ng/ml (>2x106units/mg), determined by the dose dependent stimulation of thymidine uptake by BaF3 cells expressing FGF-receptors. FGF-17 is a heparin binding growth factor that is involved in controlling tissue growth and morphogenesis. It has been found in the embryo at the midbrain-hindbrain junction, in telencephalondiencephalon transition, in the smooth muscle of major artery walls, in chondrocytes, osteoblast precursors and in mesenchymal cells.
Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
