In this completely revised and updated second edition of DNA Vaccines: Methods and Protocols, W. Mark Saltzman presents a comprehensive collection of DNA vaccine protocols, written by leading experts in the groundbreaking field of DNA vaccination. Divided into five sections, this volume contains state-of-the-art and practical procedures on the latest DNA vaccine technology. Part I contains DNA vaccine design protocols, focusing on methods that achieve optimal expression in host cells. Part II is dedicated to presenting methods for DNA delivery, and covers both the range of administration methods available for vaccine administration and a variety of techniques for improving the efficiency of delivery into cells. Part III discusses current available methods, including adjuvant and prime-boost approaches, for enhancing the potency of DNA vaccines. Part IV describes several key areas of application in the field, including allergy, avoidance of autoimmunity, and neonate and infant vaccine response. DNA Vaccines: Methods and Protocols, Second Edition concludes with a review of protocols for vaccine production and purification, and applicable quality control methods. This collection of up-to-date protocols demonstrates the tremendous progress that has been made in the field of DNA vaccination since the initial appearance of this new vaccination strategy. Given current enthusiasm for the magnificent potential for this technology among the scientific community, researchers will find tremendous value in this updated and enhanced molecular methods guide.
