Growth and characterization of poliovirus antigen chimeras

Chapter 22 outlines the construction of engineered, full-length poliovirus cDNAs in which the region encoding a well-characterized antigenic site has been replaced by sequences of choice. This chapter briefly describes the methods used to generate, maintain, and characterize infectious chimeric viruses. These techniques include several developed during the course of poliovirus study that have recently been published (1). This overview describes modifications to these techniques where relevant, but concentrates on methods not detailed by Minor (1). The production and analysis of poliovirus antigen chimeras can be readily subdivided into three discrete areas.
