..., the selectivity of microelectrodes based on this exchanger for TEA and TMA exceeds that for K + by factors of 10 7 and 10 2.7 , respectively( Oehme and Simon, 1976 ; Ammann, 1986 ). Ion-selective microelectrodes based on cation exchangers have previously been used to reveal changes in extracellular space...

...Juan P. Ianowski; Robert J. Christensen; Michael J. O'Donnell SUMMARY Intracellular ion activities ( a ion ) and basolateral membrane potential ( V bl ) were measured in Malpighian tubule cells of Rhodnius prolixus using double-barrelled ion-selective microelectrodes. In saline containing 103mmoll...

... as described previously ( Moser et al. 1979 ). Calibration of ion-selective microelectrodes (ISMs) and experiments were carried out in an experimental chamber connected to a flow-through system, which exchanged the bath volume of 0.7 ml within 5–6 s, at a temperature of 16 °C ( Fresser et al. 1991 ). From...

... mV to mmol l − 1 or pH. To present the data, the graphics program Sigma Plot 4.1 (Jandel Scientific) was used. Most of the fine steps in the illustrations are due to limitations of resolution. Experiments and calibration of ion-selective microelectrodes were performed at 16°C. Astacus...
