How many cells per ml freeze
WebResuspend cells in the appropriate volume of Freezing Medium (90% Medium with 15% FBS; 10% DMSO). Please work quickly once cells are resuspended in Freezing Medium, DMSO is toxic to cells. Place 0.5 à 1 ml/cryo vial (10 6 cells) labeled with cell type, passage number, date, number of cells and initials. WebResuspend cells in enough freezing medium to create a cell suspension of 1x106cells per ml. Pipette up and down to ensure even mixture and aliquot about 1ml into storage vials. This will provide 1x106cells per cryovial. 5. Transfer cells immediately to -20°C for one hour, followed by -80°C overnight before permanent storage in liquid nitrogen.
