Fig. 3. Comparison of the growth cycles of mutant viruses constructed by site-directed mutagenesis of the infectious clone, pGGVs. PS cells were infected with each mutant virus at an m.o.i. of 10 p.f.u./ml and supernatant medium (100 µl) was collected at different time-points. Virus titres were estimated by plaque assay. Each curve represents the average value of virus titre estimated in four parallel experiments repeated twice.
