Comparison of six different methods to calculate cell densities
WebPellet the cells by centrifugation at 300 x g for 7 minutes. Decant the supernatant. Wash the cells by pipetting 10 mL medium into each conical tube and resuspending the pellet. Collect the cells by centrifugation at 300 x g for 7 minutes. Resuspend the washed cells in complete cell culture medium. Enumerate cell density. WebPlate 200 µL of cell culture (i.e., 10,000–50,000 cells) into the wells of the sterile 96-well cell culture plate. Incubate the cells for 18 hours at 37°C. Stimulate the cells as desired. In the example presented below, HeLa cells were treated with 100 μM anisomycin for 60 minutes at 37°C. At the end of the treatment, aspirate the media ...
