Le vie conduttive per il $K^{+}$ presenti nelle membrane apicali dell'epitelio di cistifellea di coniglio vengono inibite dal $Ba^{2+}$ in concentrazioni mM. Esse sembrano perciò diverse dalle vie basolaterali degli epiteli a bassa ed alta resistenza e dai canali del $K^{+}$ delle membrane eccitabili, che sono molto più sensibili al $Ba^{2+}$.
