Abstract
Changes in intracellular calcium levels induced in mast cells by either antigen or ionomycin were monitored using flow cytometry and the calcium binding dye indo-1. Both stimuli increased calcium levels in responsive cells by a similar amount, but not all cells examined were responsive to antigen. Antigen-induced increases in intracellular calcium levels could be completely blocked by the calcium antagonist TMB-8. Flow cytometry appears to be a useful method for monitoring mast cell calcium concentrations, as it provides the capability to study large numbers of individual cells.Keywords
