Failure of 2,4,6-triaminopyrimidine (TAP) to block sodium pathways in a "leaky" epithelium: the urinary bladder of the trout.

B Fossat, B Lahlou.   

Abstract

The organic cation 2, 4, 6 - Triaminopyrimidine (TAP) used to block sodium permeability across leaky epithelia is ineffective on isolated urinary bladder of the trout. This observation suggests that this membrane does not present cation-selective paracellular pathways.
