R&D Systems Human IL-15 Recombinant Protein
Human Recombinant Protein
Manufacturer: R&D Systems 247ILB025
DescriptionMeasured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED 50 for this effect is 0.3-2.6 ng/mL. The specific activity of Recombinant Human IL-15 is approximately 4.5 x 10 5 U/µg, which is calibrated against recombinant human IL-15 WHO International Standard (NIBSC code: 95/554).
