Lineage-specific cytokine affecting the proliferation and maturation of megakaryocytes from their committed progenitor cells. It acts at a late stage of megakaryocyte development. It may be the major physiological regulator of circulating platelets. Biological Activity: Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human MO7e cells is less than 1.0ng/ml, corresponding to a specific activity of > 1.0x10e6 IU/mg.
