Fluorescent microscopy images of Huh7 cells. a Silencing vector-transfected Huh7 cells were observed in a 6-well plate after 48 h incubation before seeding into E-plate 96. b At the end of the proliferation assay, Huh7 cells on E-plate 96 were visible between microelectrodes seen as aligned closed circles. The insert represents the gold microelectrode sensors covering the bottom surface of the well (from the manufacturer’s manual)
