FIG. 6.
Growth of d13-lacZ in Vero and HEL cells. Confluent monolayers of Vero (A) or HEL (B) cells in 25-ml flasks were infected in duplicate with WT HSV-1 strain (KOS1.1), d13-lacZ, or R13-lacZ at an MOI of 10 and incubated at 37°C for 24 h. Virus yield in the infected-cell lysates was determined by plaque assay on Vero cells. The bars denote the mean virus yields for cells infected with the indicated viruses, with the error bars indicating the values of the two duplicate infections.
