Abstract
This SOP is for thawing an adherent cancer cell line from a frozen cryovial.
Select an appropriate culture media for your cell line. Common culture medias used for cancer cell lines are serum supplemented Advanced DMEM F-12 or RPMI, in the presence of pen-strep.
Equipment
Pipette boy
25ml stripette
P1000 pipette and tips
Microbiology Safety Cabinet (MSC)
Light Microscope
37 °C waterbath
37 °C , 5% CO2 incubator
Safety warnings
Retrieving vials from liquid nitrogen tanks is a significant ergonomic risk due to potential weight of filled racks. To reduce the risk of manual handling injury, lifting racks out of dewers should be kept to a minimum.
Before start
Pre-warm complete culture media to room-temperature.
Add 18ml complete culture media to a T75 flask.
Remove the cryovial from liquid nitrogen storage and place on dry-ice for transfer to cell culture lab.
Take the cryovial from the dry-ice and hold in a 37 °C waterbath until thawed.
Dry the cryovial thoroughly, spray with 70% ethanol and transfer to cell culture hood.
Use a P1000 pipette to transfer the contents of the cryovial to the T75 flask containing 18 mL media.
Use 1 mL complete culture media to wash the cryovial and add this to the flask.
Place the flask in a 37 °C , 5% CO2 incubator. Agitate the flask gently back and forth and side to side to ensure even distribution of cells across the flask.
After 24 hours, inspect adherence and confluency. Remove the media using a sterile aspirating pipette and replace with 12 mL complete culture media.
