Induced proliferation of CTLL-2 cells for Rat IL-2. Cell proliferation was measured to calculate the ED50, which is as expected less than 5 ng/ml.
Non-reducing (-) and reducing (+) conditions in a 4 - 20% Tris-Glycine gel stained with Coomassie Blue. 1 μg of protein was loaded in each lane. Rat IL-2 has a predicted Mw of 15.6 kDa.

Description

Interleukin-2 (IL-2) is an immunomodulatory cytokine that is produced by lymphocytes. IL-2 signals through the IL-2R receptor to induce activated T cell proliferation and promote T cell differentiation. IL-2 also stimulates the proliferation and differentiation of B cells, Natural Killer cells, monocytes, and macrophages.

Activity Assay

Rat IL-2 is fully biologically active when compared to standard. The activity is determined by the ability to induce CTLL-2 cells proliferation and it is typically less than 5 ng/ml.
