This book seeks to provide an overview of traditional and emerging protocols used to examine the aetiology, mechanisms and pathophysiology of GVHD, as well as those used to identify novel biomarkers and to test existing and new therapies to prevent or treat GVHD. 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, Graft-Versus-Host Disease: Methods and Protocols aims to serve as a useful resource for current and future researchers in these and other areas of health and disease.
