Table 1 Convection effect. CHL/IU cells were inoculated in wells of a 96-well plate (5000 cells/100 μL) or of a 48-well plate (10,000 cells/200 μL). After a two-day culturing period, 10 μL (96-well plate) or 20 μL (48-well plate) of CCK-8 were added to each well and OD-450 was measured 2 h after the addition of CCK-8
