Can detergent gp through a lipid bilayer
WebHowever, depending on the properties to be investigated, these systems could potentially have some key disadvantages. Detergent micelles, while able to solubilize most membrane proteins, cannot effectively mimic the physical and chemical properties of the lipid bilayer. Liposomes can be formed using a wide variety of lipids. WebCommonly used detergent-extraction methods destroy naturally associated lipid bilayers. Here, we devised a detergent-free method for preparing cell-membrane nanoparticles to study the multidrug exporter AcrB, by cryo-EM at 3.2-Å resolution.
