ProSpec-FGF 18 Mouse

Fibroblast growth factor 18, FGF-18, zFGF5, Fgf18, D130055P09Rik.

Fibroblast growth factor 18 is a member of the large FGF family which has at least 23 members. FGF18 is a heparin binding growth factor with a core 120 amino acid FGF domain which allows for a common tertiary structure. FGFs are expressed in the course of the embryonic development and in restricted adult tissues. FGF-18 is an indispensable regulator of long bone and calvarial development. FGF-18 signals via FGFR 1c, 2c, 3c, and 4.

FGF-18 Mouse Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 180 amino acids and having a molecular mass of 21kDa.
The FGF-18 is purified by proprietary chromatographic techniques.

Escherichia Coli.

Sterile Filtered White lyophilized powder.

FGF-18 protein was lyophilized from a 0.2µm filtered concentrated solution in PBS, pH 7.4.

It is recommended to reconstitute the lyophilized FGF-18 in sterile 18M-cm H₂O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

Lyophilized FGF-18 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution FGF-18 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein .
Please prevent freeze-thaw cycles.

Greater than 95.0% as determined by:
Analysis by RP-HPLC.
Analysis by -PAGE.

The ED₅₀ as determined by the dose-dependent stimulation of thymidine uptake by BaF3 cells expressing FGF-receptors is < 0.5ng/ml, corresponding to a specific activity of > 2.0×10⁶ units/mg.
