This volume covers a broad range of methods, technologies, and protocols on malaria. Chapters detail research on collecting parasites in the field, single molecule-level analyses of adhesive interactions, and focused studies aiming at disrupting the devastating disease. Written in the format of the highly successful Methods in Molecular Biology series, each chapter includes an introduction to the topic, lists necessary materials and reagents, includes tips on troubleshooting and known pitfalls, and step-by-step, readily reproducible protocols.

Authoritative and cutting-edge, Malaria Immunology: Targeting the Surface of Infected Erythrocytes aims to be a useful and practical guide to researches to help further their study in this field. Chapter Analysis of var gene transcription pattern using DBL-tags [Chapter 14] is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.

Includes cutting-edge methods and protocols Provides step-by-step detail essential for reproducible results Contains key notes and implementation advice from the experts
