It is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. IL-2\/IL-2R signaling is required for T-cell proliferation and other fundamental functions that are essential for the immune response. IL-2 stimulates growth and differentiation of B-cells; NK cells; lymphokine-activated killer cells; monocytes; macrophages and oligodendrocytes.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e:Human IL-2 Protein, Tag Free stimulates proliferation of CTLL-2 cells.
