Figure 1From: Population dynamics of an RNA virus and its defective interfering particles in passage culturesVirus production during passage cultures. (a) Virus production during fixed-volume passages (upper panel), with corresponding cell number (middle panel) and multiplicity of infection (MOI, lower panel); (b) Virus production during fixed-MOI passages for MOI of 100 (filled circles), 50 (open circles), 10 (filled triangles), 5 (open triangles), 1 (filled diamonds), and 0.1 (open diamonds); cultures were stopped when virus yields fell below levels needed to maintain the MOI.Back to article page
