Thawing mammalian cells from LN2[edit]
Andrew Richards 7/21/2016
Prep[edit]
Prepare everything before thawing cells to minimize thaw time:
- 15 ml tube with 9 ml of complete media, pre-warmed to 37 C in water bath
- Additional 10 ml of complete media, pre-warmed to 37 C in water bath
- T75 with 5 ml complete media, pre-warmed to 37 C in incubator
- 15 ml balance tube with 10 ml H2O
- 1 ml micropipette with pipette tips
Protocol[edit]
- Freeze slow, thaw fast --> To thaw from LN2, put cryotube directly into 37 C water bath and let thaw until ice is almost completely gone.
- Using 1 ml pipette, add cells dropwise to 10 ml pre-warmed media.
- Spin down at minimum rcf (1000 rpm on the small round bucket rotor in CERC) for 3 min.
- Tap the tube to loosen pellet and resuspend in 10 ml pre-warmed media.
- Transfer to T75.
