Ionomycin is an ionophore produced by the bacterium Streptomyces conglobatus. It is used in research to raise the intracellular level of calcium (Ca²⁺) and as a research tool to understand Ca²⁺ transport across biological membranes. It is also used to stimulate the intracellular production of the cytokines, interferon, perforin, IL-2, and IL-4 usually in conjunction with PMA. These cytokines are important in the inflammatory response.

Commercially, Ionomycin can be obtained as a free acid, or as a Ca²⁺ salt.
