Fig. 3From: Proteolytic cleavage analysis at the Murray Valley encephalitis virus NS1-2A junctionPlaque morphology of rMVEV and NS1-NS2A cleavage site mutant viruses. Samples of culture supernatant from BHK cells transfected with rMVEV, rP3-Gly or rP8-Ala were subjected to plaque assay on Vero cells. The corresponding plaque morphology on Vero cell monolayers stained with 0.02 % neutral red on day 4 p.i and recorded the following day are givenBack to article page
