| − | The solution was put on ice 10min (stop the OD). After, it was centrifuged 10min at 4°C at 3000rpm. The pellet was resuspended in 80mL ice-cold TB and incubated on ice for 10min. The solution was centrifuged again at 4°C at 3000rpm. The pellet was resuspended in 20mL ice-cold TB and DMSO was added at 7% of the final concentration (1.58mL of DMSO for 21mL of TB+cells). The solution was incubated on ice for 10min and then distributed in tubes, frozen in liquid nitrogen and stored at -70°C. | + | The solution was put on ice 10min (in order to stop the OD).
