Recombinant Rhesus Macaque Interleukin-3 protein (IL3) (Active)

Assay #1: Fully biologically active when compared to standard. The ED50 as determined by the dose- dependent stimulation of the proliferation of murine NFS-60 cells is less than 5.0 ng, ml, corresponding to a specific activity of 2 105 IU, mg. Assay #2: The ED50 as determined by a cell proliferation assay using human TF-1 cells is less than 0.05 ng, ml, corresponding to a specific activity of > 2.0 107 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.
