Splitting ARPE-19 cells
Before starting:
- Warm up Media+Serum, PBS, Trypsin-EDTA, and FBS in 37°C water-bath
- Place a beaker for disposing of waste in the hood
- Place appropriate T-25 Flasks and 6 well plates in the hood
1. Remove the cell media from the cells
2. Wash the cells with 5 mL of PBS
3. Remove PBS, and put in 5 mL of Trypsin (Trypsin .05%, Life Technologies, Cat. 25300054)
4. Incubate for 10 minutes at 37° and 5% CO2
5. Look at the cells using the microscope; you should see the cells detaching from the surface
6. Knock the flask to dislodge the cells
7. Put in 1 mL of FBS
8. Put the 6 mL of cells into a conical
9. Spin at 500 rpm for 3 minutes
10. Pull off the supernatant (6 mL)
11. Re-suspend in 10 mL of media
Adding cells to a T-25 flask:
- 2 mL cells + 3 mL media (add media to the flask first)
Adding cells to a 6-well plate:
- Combine 4.5 mL cells + 4.5 mL media in a 15 mL conical
- Put 1.5 mL into each well
