different types of analysis : light absorption of unstained/stained cells , forward angle light scattering ( fals ) , right angle light scattering ( rals ) or both , cell fluorescence based on dye retention or dye exclusion ( due to erythrosin b , ethidium bromide , fluorescein diacetate , rhodamine 123 ) were tested and compared , with the classical trypan blue exclusion test , for their effectiveness in the determination of cell viability .
