Simultaneous measurements of the calcium rise, membrane potential change, and 90° light scatter (shape change) responses exhibited by neutrophils upon activation, can be obtained with identical result as that obtained when independently performing each measurement. The putative intracellular mediator diacylglycerol depolarizes membrane potential and causes a decrease in light scatter. Leukotriene B causes a rise in calcium and a decrease in light scatter. The chemotactic peptide, N-formylmethionyl-leucyl-phenylalanine, causes a depolarization of membrane potential, a calcium rise, and a decrease in light scatter. The fura 2 measurements of intracellular free calcium indicate that the calcium concentration of unstimulated cells is much lower than previously thought based on quin 2 studies.
