three different preparations of mouse pancreatic fragments where all the cells tested electrophysiologically showed ( a ) complete electrical coupling ( control ) , ( b ) complete uncoupling ( after 1-to 2-min exposure to 100 % co2 ) , or ( c ) complete recoupling ( 1-2 min after removal of 100 % co2 ) were fixed , with the electrodes in situ , with 0.2 % glutaraldehyde and freeze-fractured for quantitative analysis of acinar cell gap junctions .
