This comprehensive collection of detailed protocols covers all areas of cDNA work, from library construction and manipulation to screening and analysis of resulting clones. Great care has been taken to combine up-to-date versions of some of the most widely used protocols with some very useful newer techniques. The protocols describe methods for cloning difficult-to-obtain ends of cDNAs, methods for analyzing cDNA sequence data, and methods for using the wealth of cDNA data emerging from the human genome project. Bearing in mind the importance of the library screening method to the determination of cloning strategy, the book offers a wide range of approaches to screening cDNA libraries.
