two methods were used , both based on the distribution of lipophilic fluorescent indicators : the anionic bis ( 1,3-diethylthiobarbiturate ) -trimethine oxonol ( fluorescence measurement made on whole cell suspensions ) and the cationic 3,3-dihexyloxacarbocyanine iodide ( dioc6- ( 3 ] ( using flow cytofluorimetric analysis ) .
