This fully updated volume utilizes the expertise of scientists currently engaged in immunotoxicity testing to provide the reader with lab-ready procedures and the background information needed to identify effective testing approaches. Dedicated to identifying and describing exogenous agents that can modify immune function, uncovering modes and mechanisms of action for such agents, and translating data from the laboratory and from the clinic to better predict health risks as well as benefits to those who are exposed to immunomodulatory agents, immunotoxicity testing continues to be a vital field of study, and this collection highlights both the "tried and true" methods as well as alternative protocols that have been more recently developed. Written in the highly successful Methods in Molecular Biology format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, andtips on troubleshooting and avoiding known pitfalls.
