Physical Appearance and Stability Lyophilized FGF-19 Human Recombinant although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Fibroblast Growth Factor-19 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 (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity Filtered (0.2µm) and lyophilized from 1mg/ml in 1xPBS, pH 7.4. Greater than 95.0% as determined by
Application
Solubility It is recommended to reconstitute the lyophilized FGF-19 in sterile 18M-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.
Biological Activity The ED50 as determined by the dose-dependent stimulation of the proliferation of balb/c 3T3 cells is 100-150ng/ml.
Shipping Format and Condition Lyophilized powder at room temperature.
