From: Tween-20 transiently changes the surface morphology of PK-15 cells and improves PCV2 infection
The morphologic changes of PCV2-infected PK-15 cells were observed by SEM at the indicated times of 0.03% Tween-20 post treatment. a PCV2-infected PK-15 cells without Tween-20 treatment as control. b PCV2-infected PK-15 cells at 0 h post Tween-20 treatment. c PCV2-infected PK-15 cells at 24 h post Tween-20 treatment. d PCV2-infected PK-15 cells at 48 h post Tween-20 treatment. e PCV2-infected PK-15 cells at 72 h post Tween-20 treatment.
