Recombinant Human Insulin-like growth factor-binding protein 3 protein (IGFBP3) (Active)

Fully biologically active when compared to standard. The ED50 as determined by inhibiting IGF-II induced proliferation of serum free human MCF-7 cells is less than 200 ng, ml, corresponding to a specific activity of 5.0 103 IU, mg in the presence of 15 ng, ml of rHuIGF-II.

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.
