There are many fundamental unanswered questions concerning the composition, structure, and dynamics of lateral microdomains (rafts) in biological membranes. Thus, sophisticated techniques have been used to study intact cell membranes as well as model systems composed of specific lipids and proteins thought to be in rafts. Using proven biochemical, biophysical, and computational methods, this book provides the most up-to-date information on the subject, information that promises to continue unraveling the many mysteries of the properties and formation of lipid rafts. All this makes this work an essential reference for molecular biologists, biochemists, biophysicists, and biophysical chemists.
