Antiviral activity of baicalein against DENV-2 intracellular replication. Foci forming unit reduction assay was used to evaluate the anti-dengue activity of baicalein after virus adsorption to the Vero cells (A) and the respective DENV-2 RNA copies were quantified using qRT-PCR (B). All experiments were conducted in triplicates. The percentages of foci reduction (%RF) and RNA copy number reduction were obtained by comparing against the controls maintained in parallel.
