WebThe plasma membrane is a convenient cell boundary marker commonly used for probes. Lipophilic dyes are typically used as plasma membrane stains, but they can internalize rapidly and offer a narrow window for imaging. Fluorescently labeled lectins, such as wheat germ agglutinin, have also been employed as plasma membrane stains. WebModel membrane systems are essential tools for the study of biological processes in a simplified setting to reveal the underlying physicochemical principles. As cell-derived membrane systems, giant plasma membrane vesicles (GPMVs) constitute an intermediate model between live cells and fully artificial structures. Certain applications, however, …
