Induced proliferation of CTLL-2 cells for Human IL-15. 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. Human IL-15 has a predicted Mw of 12.9 kDa.

Description

Interleukin-15 (IL-15) is a widely expressed proinflammatory cytokine that is structurally and functionally related to interleukin-2 (IL-2). IL-15 signals through JAK kinases to activate STAT3, STAT5, and STAT6 transcription factors. IL-15 regulates the activation of T cells, neutrophils, and macrophages, and is a stimulatory cytokine promoting dendritic cell function. IL-15 expression is dysregulated in chronic inflammatory disorders, including rheumatoid arthritis, psoriasis, and pulmonary inflammatory diseases. Human IL-15 shows activity on mouse cells.

Activity Assay

Human IL-15 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. This corresponds to an expected specific activity of 2 x 105 units/mg.
