After the identification of a potential protein drug, the next critical step is the production of sufficient authentic material for testing, characterization, and clinical trials, which, when successful, leads to the need for robust methodologies for large-scale production, purification, characterization, viral inactivation, and continued testing of the final protein product.  Building on the valuable first edition, Therapeutic Proteins: Methods and Protocols, Second Edition aims to cover each of these key aspects of protein drug production through the contributions of authors from highly esteemed industrial and academic institutions around the world.  Emphasizing the newest developments in the field, this second edition also includes additional emphasis on discovery, including new display and screening methods as well as the design and engineering of new types of therapeutic proteins.  There is also discussion of computational and bioinformatics methods, and chapters on safety aspects of therapeutic protein development.  Written in the highly successful Methods in Molecular Biology™ format, protocol 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.
