More Information
Product Details
Synonyms Interleukin-15
Product Type Protein
Source/Host CHO cells

The extracellular domain of human IL-15 (aa 49-162) including mutations at Q149D and Q156D is fused to the N-terminus of the Fc region of mouse IgG2a.

Crossreactivity Human
Label/Conjugates Biotin
Biological Activity

This mutant IL-15/Fc fusion protein specifically binds to the IL-15R, competitively inhibits IL-15-triggered cell proliferation, promotes transplant tolerance, does not activate the STAT-signaling pathway, and exerts a prolonged circulating half-life caused by the modified Fc domain.

Interleukin-15 (IL-15) has a broad spectrum of biological activities. It is crucial for the development, proliferation, survival and differentiation of multiple cells from both innate and adaptive immune systems. IL-15 up-regulation has a central role in the development of several autoimmune or chronic inflammatory disorders. Targeting IL-15 or its receptor may have a valuable impact on the treatment of immune-mediated diseases. IL-15 participates in the development of important immune antitumor mechanisms. It activates CD8(+) T cells, natural killer (NK) cells, NK T cells, and can promote the formation of antitumor antibodies. IL-15 can also protect T effector cells from the action of T regulatory cells and reverse tolerance to tumor-associated antigens. In pre-clinical studies IL-15 has been found to demonstrate potentiated antitumor effects following pre-association with IL-15Rα, or when used in combination with chemotherapy, adoptive therapy, monoclonal antibodies, and tumor vaccines.

Application: Useful for immunofluorescent staining and flow cytometric analysis to identify and enumerate IL-15Rα expressing cells within mixed cell populations.
