WebAfter this 60 h-culture, the cells were passed in order to start the extraction experiment, leading to P4 and P9 cells. For early passage cells, the number of passage (4) was the smallest number possible in front of all the different constraints, whereas for late passage cells, a choice was made to use P9 cells. Web3. Make sure flasks are labelled with the cell line, passage number, split ratio, date, operator initials and the vial number of the cells. Place flask(s) straight into 37°C CO 2 incubator. Write down the details of the sub-culturing in the culture record log sheet. There should be a separate log sheet for each vial of cells resuscitated and ...
