Activity: Measured in a cell proliferation assay using MO7e human megakaryocytic leukemic cells. The ED50 for this effect is typically 10-40 ng/mL.
Activity: Measured by its ability to induce IL-6 secretion by NIH‑3T3 mouse embryonic fibroblast cells in the presense of 20 ng/mL TNFα. The ED50 for this effect is 0.5-2.5 ng/mL.
