Interleukin-10 is produced by murine T-cells following their stimulation by lectins. The main source for B-cell-derived Interleukin-10 in mice are Ly-1 B-cells that express CD5 and CD11. Murine keratinocytes also produce IL10. In humans IL-10 is produced by activated CD8(+) peripheral blood T-cells, by T-helper CD4 (+) T-cell clones (resembling Th0, Th1, and Th2 ) after both antigen-specific and polyclonal activation, by B-cell lymphomas, and by monocytes following cell activation by bacterial lipopolysaccharides and mast cells. B-cell lines derived from patients with acquired immunodeficiency syndrome and Burkitt's lymphoma constitutively secrete large quantities of IL-10 into the conditioned medium. The synthesis of IL-10 by monocytes is inhibited by IL-4 and IL-10.

Endotoxin: <0.01ng/ug or <0.1EU/ug as per LAL

Biological Activity: Interleukin-10 is fully biologically active when compared to standard. The ED50 as determined by the dose-dependent stimulation of mouse MC-9 cells was found to be < 0.5ng/ml, corresponding to a Specific Activity of 3x106 IU/mg.
