This detailed volume explores methods of examining gangliosides, membrane amphiphilic lipids that are deeply involved in the modulation of the overall properties of cellular membranes, as well as of the functions of membrane-associated proteins. The contents take into account the vital availability of new enzymatic approaches, the knowledge of an incredibly extensive number of glyco-enzymes, and the improvement of multi-genetic analyses. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
