Reversal potentials obtained from CHO-K1 cells permanently transfected with r-eag under biionic conditions (Cs+ in, K+ out). Control untreated cultures have the biggest standard deviation (SD) and coefficient of variation (CV). Cells selected by the presence of mitotic figures (Taxol + HO) gave values not significantly different from taxol alone, but with smaller CVs.
