Further Information
Abbreviation:
Interleukin-2;IL-2
Accession:
P60568
Activity:
1. Measure by its ability to induce proliferation in CTLL-2 cells. The ED50 for this effect is < 0.2 ng/mL The specific activity of recombinant human IL-2 is approximately > 2. 5 x10^7 IU/mg.
2. Measure by its ability to induce proliferation in NK cells. The ED50 for this effect is < 46ng/mL.
Background:
Interleukin-2(IL-2) is an interleukin; a type of cytokine signaling molecule in the immune system;belongs to the IL-2 family. 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.
