We recently purchased CAOV4 ovarian cancer cell line from ATCC which requires growth in Leibovitz's L-15 medium. This medium is designed to be used without CO2. Does anyone have experience using this cell line with an alternative medium? If we use Leibovitz's L-15, we only have CO2 incubators. Are we able to just turn the CO2 down to 0.0% and that will be sufficient?
