This detailed collection covers methods recently developed for experiments on organisms from each of the major euglenozoan groups, including diplonemids, euglenids, and kinetoplastids. Volume 1 presents a historical review of the research into euglenozoans, followed by sections of techniques involving isolation and culturing of different species of euglenozoans, as well as a variety of -omics research methods. 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 and readily reproducible laboratory protocols, and tips for troubleshooting and avoiding known pitfalls. Authoritative and practical, Euglenozoa: Methods and Protocols, Volume 1 serves as an ideal guide for researchers working with these fascinating organisms and investigating the aspects of their extreme biology.
