Membrane proteins are key in a large number of physiological and pathological processes. Their study often involves a prior detergent solubilization step, which strips away the membrane and can jeopardize membrane protein integrity. A recent alternative to detergents encompasses maleic acid based copolymers (xMAs), which disrupt the lipid bilayer and form lipid protein nanodiscs (xMALPs) soluble in aqueous buffer. Although xMALPs are often referred to as native nanodiscs, little is known about the resemblance of their lipid and protein content to the native bilayer. Here we have analyzed prokaryotic and eukaryotic xMALPs using lipidomics and in-gel analysis. Our results show that the xMALPs content varies with the chemical properties of the used xMA. Barniol-Xicota and Verhelst investigate the usefulness of different maleic acid-based copolymers (xMAs) to solubilize membrane proteins within native-like lipid environments. They use bacterial and mammalian cell lines to study different polymer solubilisation efficiencies and focus on resultant protein content, protein-lipid ratio, and the lipid compositions obtained within the xMA nanoparticles.
