Interleukin-2 (IL-2) is an immuno-modulatory cytokine produced by stimulated T cells. IL-2 signals through the IL-2R receptor to induce proliferation of activated T cells. IL-2 also stimulates proliferation and differentiation of B cells, natural killer cells, monocytes and macrophages

Source:
Recombinant protein corresponding to 134aa from human IL-2 expressed in E.coli.

Molecular Weight:
~15.5kD

Endotoxin:
1EU/ug (LAL)

Biological Activity:
The activity is measured by the dose-dependent proliferation of CTLL-2 cells and is typically <1ng/ml.
