Characterization of H+ efflux pathways in rat hepatocytes
M. Sawkat Anwer, Kathleen Nolan – 1 July 1988 – A pH‐stat method was used to characterize H+ efflux pathways in hepatocytes in order to determine if Na+/ H+ and Ca++/H+ exchange are involved in H+ efflux from hepatocytes under basal conditions and if cyclic AMP analogs affect Na+/H+ exchange. Total H+ efflux of freshly prepared hepatocytes ranged from 10 to 15 nmoles per min per mg protein. A part of total H+ efflux (35 to 50%) was dependent on extracellular Na+.
