FIG. 5.
Growth kinetics of MHV-SGFP and MHV-WT. LR7 cells were infected with either MHV-WT or with the independent MHV-SGFP clones A or B at an MOI of 1. Viral infectivities in the culture media were determined at different times postinfection by a quantal assay on LR7 cells, and the TCID50 values were calculated.
