the durations of the ion gradients and relative ion permeabilities were determined in separate experiments by the dependence of the half time for net k+ ( or choline+ ) movement coupled with these anions ( cl- or gluconate- ) , registered by the fluorescence of 1-anilino-8-naphthalene sulfonate ( chiu , v.c.k. , haynes , d.h .
