This volume covers the latest protocols used to study the molecular biology of morbilliviruses, including cell entry, replication, and virus-host interactions. The chapters in this book also cover methods for studying morbillivirus infection through the use of novel tissue culture and in vivo models; analyzing the biological implications of infection by using primary tissues isolated from infected animals; and exploring diagnostic tools to evaluate humoral immunity against human-pathogenic measles virus (MeV). Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls.
