|Product Overview:||Recombinant Human IL2 (Ala21-Thr153) with a 6His tag at the C-terminus was produced in HEK293 cell in an animal component free process under cGMP guidelines.|
|Description:||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.|
|Bio-activity:||Measured in a cell proliferation assay using CTLL‑2 mouse cytotoxic T cells.
The ED50 for this effect is typically 0.02-0.3ng/mL. Specific Activity of 1.0 x 10^7 IU/mg.
