Recombinant Human Fibroblast growth factor 4 protein (FGF4) (Active)

Fully biologically active when compared to standard. The ED50 as determined by thymidine uptake assay using FGF?receptors transfected BaF3 cells is less than 0.5 ng, ml, corresponding to a specific activity of 2.0 106 IU, mg.

The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
