MDCK cells were infected with influenza viruses, including A/GIRD02/09 (H1N1), A/Aichi/2/68 (H3N2) and A/PR/8/34 (H1N1) (H274Y mut) at 0.01 MOI for 2 h at 34 °C. After viral adsorption, cell monolayer was covered with overlay medium containing LH-C in different concerntration. After incubation for 72 h, the cells were fixed and stained with crystal violetBack to article page
