The central role of RNA in many cellular processes, in biotechnology, and as pharmaceutical agents, has created an interest in experimental methods applied to RNA molecules. This book provides scientists with a comprehensive collection of thoroughly tested up-to-date manuals for investigating RNA-protein complexes in vitro. The protocols can be performed by researchers trained in standard molecular biological techniques and require a minimum of specialized equipment. The procedures include recommendation of suppliers of reagents.
