Cytoplasmic, free Mg2+ was measured spectrophotometrically using an intrasynaptosomally entrapped Mg2+-indicator, Eriochrome blue (EB). Addition of the ionophore A23187 or disruption of the synaptosomal plasma membrane with digitonin caused an increase in absorbance of entrapped EB with a maximum at
