Two types of cation channels in the basolateral cell membrane of human salivary gland acinar cells

Giga-seal patch-clamp single-channel current recording was applied to the basolateral cell membrane of human salivary gland acinar cells. The results indicate that the presence of Ca2+- and voltage-activated K+-channel having a unit conductance of 160 pS and Ca2+-activated Na+ permeable channel, having a unit conductance of 15 pS.
