Lipoparticles have many advantages in isolating membrane proteins: firstly, they are homogeneous and physically well defined, capable of maintaining the native structures of target membrane proteins in high densities; secondly, they can be used to detect membrane protein interactions and therefore have wide applications in antibody screening, phage and yeast display, immunogens production and ligand binding assays. https://www.creative-biostructure.com/vlp-construction-40.htm
