This detailed volume explores methods and techniques reflecting how viruses can be a beneficial force for all levels of life as well as the mammalian microbiota. Beginning with methods for the development and study of viruses, the book continues with current techniques and approaches used to develop new treatments from virus-derived vaccines to vectors and proteins, such as a range of models and methods designed to measure therapeutic efficacy of virus-derived biologics and therapeutic proteins. Written for the highly successful Methods in Molecular Biology series, 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.  Authoritative and practical, Viruses as Therapeutics: Methods and Protocols is an ideal guide for researchers working to further understand how viruses can benefit lifeforms and even prevent damage from other viruses.
