...Horst Onken; Martin Tresguerres; Carlos M. Luquet SUMMARY Split lamellae of posterior gills of Chasmagnathus granulatus adapted to 2.5‰ salinity were mounted in a modified Ussing chamber. With NaCl-saline on both sides of the preparation a transepithelial voltage( V te ) of 4.1±0.5 mV (outside...

... transbranchial potential difference ( V te ), which stabilises at positive or negative values. Ouabain shifts V te to more positive values. When mounted in an Ussing chamber, distal split lamellae generate a negative, Cl – -dependent short-circuit current ( I sc ). Na + substitution leads to more negative values...
