Figure 2: Comparison of virus in flow through fractions collected from an Eshmuno Q anion exchange chromatography column that had been loaded and spiked using methods 1-5. The bars represent the total MMV remaining in fractions 1-4 and the final buffer wash. Arrows indicate that no detectable virus could be recovered. Although the virus spike was delivered at different concentrations, approximately 8 log10 TCID50 MMV was loaded onto each column. Each bar represents the mean of two runs.
