A study of tetraphenylborate transport through rat brain lipids impregnated filter-membranes

Summary The electrical properties of rat brain lipids impregnated filtermembranes exposed to the lipophilic ion tetraphenylborate (TPhB⁻) have been studied, using electrical relaxation techniques. The state of TPhB⁻ transport system depends on the applied voltage. It was also found that the initial membrane conductance depends on the applied voltage and changes with the concentration of TPhB⁻. Our results are presented in comparison with the electrical properties of BLM exposed to TPhB⁻. To speed up publication, the authors of this paper have agreed to not receive the proofs for correction.
