Interleukin-2, active (Il2), Recombinant, Mouse

Produced by T-cells in response to antigenic or mitogenic stimulation, this protein is required for T-cell proliferation and other activities crucial to regulation of the immune response. Can stimulate B-cells, monocytes, lymphokine-activated killer cells, natural killer cells, and glioma cells. Biological Activity: Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine CTLL-2 cells is less than 0.2ng/ml, corresponding to a specific activity of ? 5.0x10e6 IU/mg.
