A Variant of Adenovirus 12 Producing Cytoplasmic Accumulation of Capsid Proteins

Abstract
A variant of adenovirus type 12 (R-Ad12) has been isolated by infecting a clonal line of normal rat kidney cells (NRK) with wild-type adenovirus 12. Although R-Ad12 failed to produce infectious progeny virions when cycled a second time through NRK cells, it nevertheless retained the ability to code for virus structural proteins that accumulated in the cytoplasm.
