Media:
IMDM (500mL) with:
- 20% FBS (100mL)
- Pen/strep (5mL)
- .05mM BME (1.77uL)
Thawing:
Day 1:
- Cells are kept in the orange Liquid Nitrogen tank, Rack 3, Box 2 (counting from bottom up)
- Do NOT warm media in a water bath; media should be at room temp so as to not stress the cells
- Thaw the vial in a water bath
- Do NOT let the vial completely thaw in the water bathKeep lid out of water bathGently move vial side to side as thawing
- It should be less than 1-2min
- Spray tube with EtOH to decontaminate, bring into the hood
- Slowly add RT media to the cells
- For 1mL frozen cells, use 19mL of fresh media
- Transfer thawed cells into the tube of fresh media as they become fully thawed
- Transfer 20mL of media+cells into a 75cm2 Flask
- Label lid with the passage number, cell type, date, and initials (if new vial label with lot number)
- Place flask with cells in the incubator
- 37C, 95% Air, 5% CO2
Day 2:
- Check on cells by using the microscope
- Change media to remove any remaining cryoprotective agent
- Collect media + cells into a falcon tube to spin down
- Spin at 125xg for 5min
- Remove old media
- Add 20mL of warmed media to the falcon tube with the cells
- Transfer cells+media to the flask (can reuse the same flask they were in, to begin with)
- Return flask to the incubator
