|Indicator||µM *||Time *(min)||
|* CHO cells stably transfected with rat muscarinic M1 receptors were loaded with fluo-3 AM or fluo-4 AM according to standard protocols, with variations in indicator concentration (µM) and incubation time, as shown. † Relative fluorescence intensities after subtraction of background fluorescence. ‡ Cells were stimulated by addition of the muscarinic agonist carbachol (50 µM). § Ratio of stimulated to basal fluorescence intensities.|
