Lipid rafts are small membrane domains containing high level of cholesterol and sphingolipids. Lipid rafts have been found in plasma membrane (PM) and internal organellar membranes such as mitochondria-associated membrane (MAMs) and endoplasmic reticulum. Lipid rafts are implicated in numerous cellular processes such as signal transduction, membrane trafficking and protein sorting.  Lipid-modified proteins and some transmembrane proteins are concentrated in the rafts while other proteins are excluded. Lipid rafts are also found to be associated with Na+/K+ ATPase on PM. Traditional methods for lipid raft isolation involve isolation of detergent resistant membrane subdomain from total membranous structures, which does not distinguish plasma membrane-derived and/or organelle-derived lipid rafts. Using the patented spin-column-based technologies, we have developed this kit specifically for isolation of plasma membrane-derived lipid rafts. Larger plasma membrane vesicles are first isolated and treated with a non-ionic detergent containing buffer followed by isolation of detergent resistant fraction by flotation centrifugation using a table top microcentrifuge. Highly enriched plasma membrane derived lipid rafts can be obtained in about 1 hour without using traditional homogenizer and ultracentrifugation.
