| Cryopreservation： | CRYOPRESERVATION:xa0 Only young cells (rings) can be frozen in glycerolyte medium** because their membranes are more robust. 1.xa0xa0xa0xa0 Centrifuge ring-stage culture for 5 mins. at 1000 x g in 50 ml centrifuge tube. 2.xa0xa0xa0xa0 Aspirate supernatant using sterile Pasteur pipet. 3.xa0xa0xa0xa0 Resuspend pellet gently in remaining supernatant. 4.xa0xa0xa0xa0 Slowly add 5 volumes of glycerolyte medium to 3 volumes pellet dropwise via a syringe as follows: xa0xa0xa0xa0xa0xa0xa0 A.xa0xa0xa0 Add the first volume of glycerolyte and allow the tube to stand for 5 mins. at room temperature. B.xa0xa0xa0 Add the remaining 4 volumes of glycerolyte and gently agitate. 5.xa0xa0 Aliquot mixture into Nunc screw-capped freezing vials and place in a Nalgene 1C cooling apparatus.
