Spectrofluorimetric estimation of extent of stimulation of [Ca2+]
in PMNL. Extent of stimulation of calcium over the basal level in fMLP or C5a stimulated CML and normal PMNL. Ratios of the total calcium in PMNL after stimulation or addition of EGTA and MnCl2 to the basal level were calculated. X-axis indicates the treatment given to the cells and Y-axis indicates average of ratios.
