-
Freezing
For optimum results, cells for cryopreservation should be in log phase of growth. Similar or standard freezing protocols may be substituted.
- Examine and make sure the cell culture free of contamination, in healthy situation and proper confluency, etc.
- Perform a cell count to determine the viability of cells.
- Gently pellet the cells centrifugation (3 - 5 minutes at 1,000~2,000rpm, 4℃). Remove the supernatant using a aspirator.
- Gently suspend the cells with CELLBANKER® cryopreservation medium (1 ml for 5×105 - 5×106 cells.
- Dispense the cell suspension in 1ml aliquots to cryopreservation vials that have been labeled with the cell line name, cell concentration, passage date and other essential information.
- Place the vials directly in a -80℃ for storage. If necessary, transfer the frozen vials to a liquid nitrogen storage tank after the vials have been frozen for at least 24 hours.
- IMPORTANT: Optimum protocol may change with the cell types.
-
Thawing
- Remove the frozen cell from storage and quickly thaw in a 37℃ shaking waterbath.
- Immediately dilute and gently mix each 1ml of cells with 10ml of complete cell culture medium.
- Gently pellet the cells centrifugation (3-5 minutes at 1,000 - 2,000rpm, 4℃). Remove the supernatant aspirator.
- Gently suspend the cells with appropriate volume of complete cell culture medium. And plate in a culture flask.
- Continue the further culture procedures according to standard protocols.
- Storage and Stability
- Store at 2 to 8 or below -20 degrees celisus. The product will be stable for 3 years after the date of manufacture at this storage temperature.
