Controlled rate freezer mammalian cells
WebThe basic principle of successful cryopreservation and resuscitation is a slow freeze and quick thaw. Although the requirements may vary amongst cell lines, as a general guide cells should be cooled at a rate of –1 °C to –3°C per minute and thawed quickly by incubation in a 37 °C water bath for 3-5 minutes. WebControlled-rate freezing, a method that involves a gradual cooling rate of -1°C/minute, before long-term storage can help maximize cell viability and integrity. Controlled-rate freezing can be achieved by using a controlled …
