Effects the PLC inhibitor, U73122, and the PI3 kinase inhibitor, wortmannin, on ligand-stimulated release of Ca2+ from intracellular stores. Cells were pre-incubated for 5 min in the absence or presence of either 1 μM U73122 or 200 nM wortmannin prior to addition of Y16-DNP3 (a), Y46-DNP (b), or 1 μg/mL DNP-BSA (c) as in Fig. 5.
