Glycerol for freezing aliquots
We use sterile 80% glycerol in water. We dilute this 1:3 (400ul 80% glycerol; 1200ul culture) for creating freezer stocks with a final glycerol concentration of 20%.
10x PBS
Used to create 1x PBS for dilution or washing cells of any species.
For 1 liter:
- NaCl 80g
- KCl 2g
- Na2HPO4 14.4g
- KH2PO4 2.4g
Stir salts with MilliQ water. This may take a significant time to dissolve!
Adjust pH with NaOH to 7.4. This will take a significant amount of NaOH; add in 200ul increments.
