(A) The biological activity of Human Recombinant IL-13 was tested by its ability to promote the proliferation of TF-1 cells. Cell proliferation
was measured after 62 hours of culture 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 above example is 3 - 4 ng/mL.
(B) 1 ug of Human Recombinant IL-13 was resolved with SDS-PAGE under reducing (+) and non-reducing (-) conditions and visualized by Coomassie Blue staining. Human Recombinant IL-13 has a predicted molecular mass of 12.6 kDa.
