Description
Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50 for this effect is 0.3-2.6 ng/mL. The specific activity of Recombinant Human IL-15 is approximately 4.5 x 105 U/μg, which is calibrated against recombinant human IL-15 WHO International Standard (NIBSC code: 95/554). Specific activity is for reference purposes only and is not routinely tested.Specifications
