Intracellular Cl^- Activity of Canine Submandibular Gland Cells: An In Vitro Observation

Abstract

Intracellular Cl^- activity (aⁱ_Cl) and transmembrane potential (ΔΨ_m) of canine submandibular gland cells were measured in vitro by using Cl^- sensitive liquid membrane microelectrodes. Under the conditions of superfusion with a control solution, average Cl^- activity of the resting cells was slightly higher than those predicted from Nernstian equilibrium.
