Please see the product label for the expiry date of your product.
Cryopreservation:
- Aspirate medium.
- Wash with PBS and aspirate PBS.
- Add Trypsin/EDTA (TE) solution to the cells and incubate at room temperature or 37°C for 5-10min, or until the cells detach.
- Examine the cells under a microscope. When the cells start to detach, gently tap the side of the vessel to loosen the remaining cells.
- Resuspend cells in 2% FBS in PBS and transfer to a 15ml conical bottom tube.
- Centrifuge cells at 200×g for 4min.
- Aspirate supernatant and gently resuspend cell pellet in Freezing medium (approx. 1Mio. cells/ml).
- Transfer cell suspension into cryovial(s) and place them into a freezing container (“Mr.Frosty” or similar).
- Place the freezing container at-80°C for 16-24h.
- Transfer cryovials to liquid nitrogen vapor for long-term-storage.
