Ionomycin is a potent and selective calcium ionophore agent (1,2). The molecule acts as a motile Ca2+ carrier and enhances Ca2+ influx by direct stimulation of store-regulated cation entry across biological membranes (3). At the micromolar level, ionomycin can activate Ca2+/Calmodulin dependent kinase and phosphatase to stimulate gene expression (4). In human T cells, ionomycin induces hydrolysis of phosphoinositides and activates PKC to mediate T cell activation (5). Ionomycin treatment of human B cells induces the activation of calcium-dependent endonuclease and results in apoptosis (6). Ionomycin treatment of bovine aortic endothelial cells (BAECs) induces rapid dephosphorylation of eNOS at Thr495 and mediates eNOS activation (7).
