Summary

Traduzione automatica

Courant ionique des canaux BK est enregistrée en utilisant des techniques de patch-clamp. Canaux BK sont exprimés en<em> Ovocytes de Xenopus</em> En injectant de l'ARN messager. La solution intracellulaire pendant les enregistrements de patch-clamp est contrôlé par un système de perfusion.
