Description: This Mouse IL-2 High Sensitivity ELISA contains the necessary reagents, from pre-coated plates to standards, buffers and diluents for performing quantitative enzyme-linked immunosorbent assays (ELISA). This ELISA kit is specifically engineered for sensitive and precise measurement of IL-2 protein levels from samples including serum, plasma, and supernatants from cell cultures.
Interleukin-2 (IL-2) plays a central role in the activation and proliferation of lymphocytes that have been primed by antigens. IL-2 plays a pivotal role in for the expansion of most T-cells, natural killer cells and B-cells during certain phases of their response. Antigen-specific proliferation of helper and cytotoxic T-lymphocytes following stimulation is critically dependent on IL-2 expression, secretion, and binding to receptors in an autocrine fashion on the surface of T cells. Apart from its most important role to mediate antigen specific T lymphocyte proliferation, IL-2 modulates the expression of interferon gamma and major histocompatibility antigens, stimulates proliferation and differentiation of activated B and NK cells, augments natural killer cell activity and inhibits granulocyte-macrophage colony formation. Alterations in the ability of T cells to synthesize IL-2 have been observed in physiologic and pathologic states.
