Differential effects of [Au(CN)2]− and [Ag(CN)2]− on Cys-less CFTR. Exposure to [Au(CN)2]− (1 mM) produced a “lyotropic” block that was not altered by exposure to KCN (1 mM). Exposure to [Ag(CN)2]− (1 mM) produced a substantially smaller block that was exacerbated by adding KCN in the continued presence of [Ag(CN)2]−.
