Abstract:SUMMARYRecovery and specific infectivity of infectious RNA from cowpea chlorotic mottle virus of low specific infectivity (14 to 2I day infections) were greatly improved by using antioxidants during virus purification and RNA extraction, and by disrupting coat protein with pronase before phenol-SDS extraction. Total infectivity of RNA from virus of low infectivity was increased over 30 times. RNA profiles obtained using polyacrylamide gels were then similar for virus with high (4 to 7 day infections) or low sp… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
