Sterile SDS stocks (40 times the treatment concentration) were added to virus aliquots to achieve the treatment concentration.
Following virus treatment, treated virus stocks were further diluted 1:1,000 in order to dilute the detergent; the cells in all plates remained viable.
In experiment 1, virus and SDS were mixed and incubated at 37°C for 30 min; in experiment 2, virus and SDS were mixed and incubated at 37°C for 10 min. ND, not done. In control plates without BPV-1, no foci appeared.
