Flow cytometric analyses of Cs⁺ and Sr²⁺ toxicity. Exponential phase cells (equivalent to OD_{600 nm} 1) were exposed to 0-400 mM of Cs (a) or Sr (b) for 24 h, stained with propidium Iodide (PI) and thiazole orange (TO) and were gated on combined parameters of FSC, SSC and FL2 (see text for details). Data points represent percentage subpopulation of live, injured and killed cells with varying concentrations of Cs⁺ and Sr²⁺ with corresponding standard error values
