Ionomycin was isolated from Streptomyces conglobatus as a potent antibiotic selective for Gram +ve bacteria. During the isolation it was recognised that ionomycin exhibits a very high affinity and selectivity for calcium ions suggesting the metabolite acts as a calcium ionophore. More recently, ionomycin has been used in cell biology as a universal calcium ionophore to explore the role of calcium regulation in the cell.
