Reagents
Glycerolyte medium**
Glycerol: 57.00 g
NaC3H5O3 (Sodium lactate): 1.60 g
KCl: 30.00 mg
NaH2PO4: 1.38 g
Glass distilled water: 100.00 mL
Mix well and adjust pH to 6.8 using concentrated NaOH and/or HCl. Autoclave and store at 4°C.

Harvesting and Preservation
Only young cells (rings) can be frozen in glycerolyte medium** because their membranes are more robust.
  1. Centrifuge ring-stage culture for 5 mins at 1000 x g in 50 mL centrifuge tube.
  2. Aspirate supernatant using sterile Pasteur pipet.
  3. Resuspend pellet gently in remaining supernatant.
  4. Slowly add 5 volumes of glycerolyte medium to 3 volumes pellet dropwise via a syringe as follows:
    1. Add the first volume of glycerolyte and allow the tube to stand for 5 mins. at room temperature.
    2. Add the remaining 4 volumes of glycerolyte and gently agitate.
  5. Aliquot mixture into Nunc screw-capped freezing vials and place in a Nalgene 1°C cooling apparatus. Place the apparatus at -80°C overnight and then plunge ampules into liquid nitrogen.  (The cooling rate in this apparatus is approximately -1°C/min.).
  6. Plunge vials into liquid nitrogen (-196°C) the next day and store in liquid nitrogen or liquid nitrogen vapor.
