| Subcultivation: | Protocol: ATCCNO: 50204 SPEC: Aseptically transfer 0.1 ml of the culture to 5.0 ml of fresh medium in a 16 x 125 mm screw-capped test tube. Incubate cultures upright at 25C with the caps on loosely. Transfer cultures every two weeks. |
| Cryopreservation: | 1.xa0 Harvest cells from a culture that is at or near peak density by centrifugation at 800 x g for 5 min. 2.xa0 Adjust the concentration of cells to 2 x 106 - 2 x 107/ml in fresh medium. 3.xa0 While cells are centrifuging prepare a 22% (v/v) solution of sterile DMSO in fresh medium. 4. Mix the cell preparation and the 22% DMSO in equal portions. Thus, the final concentration will be 106 - 107 cells/ml and 11% (v/v) DMSO. The time from the mixing of the cell preparation and methanol stock solution to the beginning of the freezing process should be no less than 5 min and no greater than 15 min. 5.xa0 Dispense in 0.5 ml aliquots into 1.0 - 2.0 ml sterile plastic screw-capped cryules (special plastic vials for cryopreservation). 6.xa0xa0 Place the vials in a controlled rate freezing unit.xa0 From room temperature cool at -1°C/min to -40°C.xa0 If the freezing unit can compensate for the heat of fusion, maintain rate atxa0xa0xa0xa0xa0xa0xa0 -1°C/min through the heat of fusion.xa0 At -40°C plunge into liquid nitrogen. Alternatively, place the vials in a Nalgene 1°C freezing apparatus.xa0 Place the apparatus at -80°C for 1.5 to 2 hours and then plunge ampules into liquid nitrogen.xa0 (The cooling rate in this apparatus is approximately xa0xa0xa0xa0xa0 -1°C/min.) xa0 7.xa0 The frozen preparations should be stored in either the vapor or liquid phase of a nitrogen refrigerator. Frozen preparations stored below -130°C are stabile indefinitely. Those stored at temperatures above -130°C are progressively less stabile as the storage temperature is elevated. Vials should not be stored above -55°C. 8.xa0xa0 To thaw a frozen ampule, place it in a 35°C water bath such that the lip of the ampule remains above the water line. Thawing time is approximately 2 to 3 minutes.xa0 Do not agitate the ampule.xa0 Do not leave ampule in water bath after thawed. 9.xa0xa0 Immediately after thawing, aseptically transfer contents to a 16 x 125 mm screw-capped test tube containing 5 ml of ATCC Medium 1651. 10.xa0xa0xa0xa0xa0xa0xa0xa0xa0 Incubate the tube on a 15° horizontal slant with the cap screwed on loosely (loosened one half turn) at 25°C. |
