WebMembrane proteins are usually purified as protein-lipid-detergent complexes. The solubility of the complexes in an aqueous environment allow the application of essentially … WebIsolation of detergent-resistant membranes (DRMs; also known as detergent-insoluble glycolipid-enriched membranes [DIGs] or glycolipid-enriched membranes [GEMs]) that …
WebDec 1, 2006 · Lipid rafts are liquid-ordered (lo) phase microdomains proposed to exist in biological membranes. Rafts have been widely studied by isolating lo-phase detergent-resistant membranes (DRMs) from … Webdetergent. Detergents with a relatively high HLB value of 12– 20 are recommended in order to solubilize membrane proteins in a non-denatured condition (24). Detergents belonging to the class of nonionic and zwitterionic detergents have become popular for their ability to solubilize membrane proteins with retention of function.
WebTo this end, detergent-solubilized cell lysates were coupled with the yeast surface display platform to affinity mature an anti-transferrin receptor (TfR) single-chain antibody (scFv). Lysates were generated from TfR-expressing HEK293 cells by solubilization with detergent-containing buffer after undergoing plasma membrane-restricted biotinylation. WebAlternatively, protein-detergent complexes could be bound to an affinity matrix and eluted following washing and/or exchange with a different detergent. Affinity matrixes with immobilized ligands for receptor binding or a variety of lectin columns highly specific for binding to subsets of glycosylated membrane proteins are suitable for these ...
WebDespite the great importance of membrane proteins, structural and functional studies of these proteins present major challenges. A significant hurdle is the extraction of the functional protein from its natural lipid membrane.
