Interleukin-2 (IL-2) is a cytokine produced by activated T cells in response to antigen stimulation. IL-2 is important for proliferation of lymphocytes, natural killer cells and macrophages and in the differentiation of CD4+ cells into Th1 and Th2 effector cells. The effects of IL-2 are mediated by the signalling activated by its binding to IL-2 receptor (IL-2 R). IL-2 activates key signalling pathways such as MAPK, JAK/STAT as well as PI3K/Akt. Activation of these pathways modulates production of inflammatory cytokines, survival and progression through cell cycle Monoclonal Anti-Interleukin-2 recognizes murine Interleukin-2. It does not react with human IL-2, but will react with rabbit IL-2 at a 100x higher IgG concentration.
Immunogen
purified, E. coli-derived recombinant mouse interleukin-2.
Application
Anti-interleukin-2 antibody may be used for immunoblotting at a working concentration of 0.1-0.2 μg/ml. The antibody is suitable for murine IL-2 neutralization assays.
Physical form
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline with 5% trehalose.
Although interleukin-2 (IL-2) was initially characterized as the primary T-cell growth factor following in vitro activation, less is known about its role in shaping T-cell responses to acute infections in vivo. The use of IL-2- or IL-2-receptor-deficient mice is problematic

The acquisition of long-term survival potential by activated T lymphocytes is essential to ensure the successful development of a memory population in the competitive environment of the lymphoid system. The factors that grant competitiveness for survival to primed T cells
Studies of the biology of the IL-2 receptor have played a major part in establishing several of the fundamental principles that govern our current understanding of immunology. Chief among these is the contribution made by lymphokines to regulation of the
Recent work has identified a new subset of effector T cells that produces interleukin (IL)-17 known as T helper 17 (Th17) cells, which is involved in the pathophysiology of inflammatory diseases and is thought to be developmentally related to regulatory
Interleukin-2 (IL-2) has multiple, sometimes opposing, functions during an inflammatory response. It is a potent inducer of T-cell proliferation and T-helper 1 (Th1) and Th2 effector T-cell differentiation and provides T cells with a long-lasting competitive advantage resulting in the
