Reversal Potentials

		Reversal potential
Treatment		Mean		SD		CV		n		Range
		mV		mV						mV
None		24.5		21.2		0.9		16		88
0.5% FCS		16.5		9.8		0.6		19		34
Taxol		32.6		8.3		0.3		15		33
Taxol + HO		37.8		5.0		0.1		5		13

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.
