Data and Publications
(A) The biological activity of Rat Recombinant IL-3 beta was tested by its ability to promote proliferation of NFS-60 cells. Cell proliferation was measured using a fluorometric assay method. The EC50 is defined as the effective concentration of the growth factor at which cell proliferation is at 50% of maximum. The EC50 in the example above is less than 5 ng/mL. (B) 5 μg of Rat Recombinant IL-3 beta was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Rat Recombinant IL-3 beta has a predicted molecular mass of 16.3 kDa.
