a significant augmentation of the binding resulted from the addition ( 20 mm ) of various anions known to penetrate the anion channels such as bromide , iodide , nitrate , bicarbonate and thiocyanate in a permeability related manner , while that of non-permeable anions including fluoride , sulfate , acetate , formate , phosphate , oxalate , lactate , succinate and tartarate had no such a profound effect on the binding .
