I have kept cells in -80 for several months, can I transfer them to liquid nitrogen now after all this time? I am afraid they would not survive.. I appreciate your input
Yes, that can be done safely and for the best storage of your cells. Most researchers will prefer LN2 to -80c. It will keep your cells viable for longer.
It should be ok. You can keep & use later on. - 80 degree C, commonly use for short time use e.g 1-3 months. LN for longer periods of time. Best of luck!
