We could not digest the weakly
amplified 161-bp product with Nhe I enzyme from complexes
immunoprecipitated from uninfected cells (Fig. 5, lanes 7 and
8) or from RV-infected cells (Fig. 5, lanes 9 and 10) by using
nonimmune sera. A nonspecific PCR product (-200 bp) was
observed in all immunoprecipitation reactions, regardless of
antisera used (Fig. 5, lanes 1-10).
