Fig. 4From: Identification of molecular determinants of cell culture growth characteristics of Enterovirus 71Quantification of plaque forming units by EV-A71 mutants 158, 475, 486, 487, 5262, partial deletant (PD) and the wild type EV-A71 strain 41. The negative control represents uninfected RD cells. EV-A71 mutants were transfected at a MOI of 0.1. The plaque assays were performed on monolayer RD cells incubated at 37 °C and were repeated at least two separate timesBack to article page
