Figure 1From: Mechanisms of the action of povidone-iodine against human and avian influenza A viruses: its effects on hemagglutination and sialidase activitiesInhibitory effect of PVP-I on influenza viral infection in MDCK cells. (A) A simplified diagram of the infection assay used in this study. (B) Quantification of viruses in cells at Ex355/Em460 is expressed as percent virus yield (left Y axis) and percent inhibition (right Y axis) of untreated infected cells.Back to article page
