Figure 2From: Cell surface sialylation affects binding of enterovirus 71 to rhabdomyosarcoma and neuroblastoma cellsThe infection and replication of EV71 to RD cells are affected by neuraminidase treatment investigated with EV71-GFP infection. Cells pretreated with or without neuraminidase (5 mU and 25 mU) were infected with or without EV71-GFP. The cell number, CPE, and fluorescence intensity were observed by fluorescence microscope. After 48 hours, higher fluorescence intensity was found in untreated cells than neuraminidase pretreated cells.Back to article page
