Ionomycin, Calcium Salt #9995

    Product Information

    Product Usage Information

    Ionomycin, calcium salt is supplied as 2.5 mg powder. Store at or below -20ºC. Before use, dissolve powder in 1.1 ml DMSO to make a 3 mM ionomycin stock solution. For working concentrations of 1 μM-3 μM, dilute DMSO stock 1:3000 to 1:1000. Treat cells with the desired concentration for intended time.

    Storage

    Store lyophilized or in solution at -20ºC, desiccated. Protect from light. In lyophilized form, the chemical is stable for 24 months. Once in solution, use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles.

    Background

    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).
