The new fifth edition of the highly acclaimed Handbook of Experimental Immunology has been completely restructured and extensively revised to reflect the considerable increase in the importance of immunology as a research discipline. Produced in four volumes, which are available for separate purchase, or as a set, the text provides a complete reference which includes experimental protocols and explications of general principles. Each section contains overviews, and chapters describing the background and technical detail of a comprehensive range of immunological procedures in immunochemistry, cellular immunology, genetics and molecular immunology, and the application of immunological methods. It is also available on CD-ROM. All material available within the four-volume text can be found on this dualplatform CD-ROM including the extended indexing and cross-referencing possible with electronic media. The CD-ROM also comprises several lengthy and highly informative contributions that were abridged in the printed version. Additional notes and illustrations that extend the scope of the material presented, and a statistical software package that complements the statistical section of the printed version are also included.
