Single Molecule Methods for Monitoring Changes in Bilayer Elastic Properties
1Department of Physiology and Biophysics, Weill Cornell Medical College, 2Department of Physiology and Biophysics, Weill Cornell Medical College of Cornell University
Membrane protein function is regulated by the cell membrane lipid composition. This video-article details how to form a patch using bilayer patch electrodes, as well as how to use gramicidin channels as reporters of altered membrane properties.

Preparation of Artificial Bilayers for Electrophysiology Experiments
Department of Physiology and Biophysics, Weill Cornell Medical College of Cornell University
Planar lipid bilayers, also called artificial lipid bilayers, allow you to study ion-conducting channels in a well-defined environment. Here, we demonstrate the individual steps needed to prepare the bilayer chamber, the electrodes and how to test that the bilayer is suitable for single-channel measurements.
