Preparat liposomów olbrzymich do obrazowania i elektrofizjologii patch-clamp

Overview

This article describes a method for preparing giant unilamellar vesicles that maintain the functional integrity of membrane proteins. The process involves depositing lipids onto a conductive surface, evaporating the solvent, rehydrating the lipid film, and applying an oscillating voltage to generate the vesicles.
