title: Virus-like 30S RNA is selectively packaged by Kirsten leukemia virus in virions of smaller size class. Brief report.
abstract: Virus particles containing Kirsten murine leukemia virus 38 S RNA and a pseudotyped virus-like cellular 30 S RNA, were partially separable. This provides a means for enriching a population of virions for those containing 30 S RNA.
