Cryopreservation Harvest and Preservation
Harvest cells from a culture that is at or near peak density by centrifugation at 800 x g for 5 min. The cells grown in a medium containing agar are concentrated by centrifugation, a solid pellet does not form. The soft pellet is resuspended to desired cell concentration with agar-free supernatant.
Adjust the concentration of cells to 2 x 106  to  2 x 107/mL in fresh medium.
While cells are centrifuging prepare a 10% (v/v) solution of sterile DMSO in fresh medium.
Add 1.0 mL of DMSO to an ice cold 20 x 150 mm screw-capped test tube.
Place the tube on ice and allow the DMSO to solidify (~5 min) and then add 9.0 mL of ice cold medium.
Invert several times to dissolve the DMSO.
Allow to warm to room temperature.
Mix the cell preparation and the DMSO in equal portions. Thus, the final concentration will be 106 to  107 cells/mL and 5% (v/v) DMSO. The time from the mixing of the cell preparation and DMSO stock solution before the freezing process is begun should no less than 15 min and no longer than 30 min.
Dispense in 0.5 mL aliquots into 1.0 mL to 2.0 mL sterile plastic screw-capped cryules (special plastic vials for cryopreservation).
Place the vials in a controlled rate freezing unit.  From room temperature cool at -1°C/min to -40°C.  If the freezing unit can compensate for the heat of fusion, maintain rate at -1°C/min through the heat of fusion.  At -40°C plunge into liquid nitrogen. Alternatively, place the vials in a Nalgene 1°C freezing apparatus.  Place the apparatus at -80°C for 1.5 to 2 hours and then plunge ampules into liquid nitrogen.  (The cooling rate in this apparatus is approximately -1°C/min.)  
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.
To establish a culture from the frozen state place an ampule in a water bath set at 35°C. Immerse the vial just to a level just above the surface of the frozen material. Do not agitate the vial.
Immediately after thawing, do not leave in the water bath, aseptically remove the contents of the ampule and inoculate a 16 x 125 mm screw-capped test tube containing either 9 mL of ATCC medium 361 (completed with serum) or 13 mL ATCC Medium 2154 adjusted to pH 6.0.
Incubate the culture at 35°C with the cap screwed on tightly (tube should be vertical for medium 361 or on a 15° horizontal slant for medium 2154).

安瓿瓶冻干管打管说明
 
一、打管说明
1、安瓿瓶开封:用浸过75%酒精的脱脂棉擦净安瓿管,用火焰加热其顶端,滴少量无菌水至加热顶端使之破裂,用锉刀或者镊子敲下已破裂的安瓿管顶端。
2、菌株恢复培养:用无菌吸管吸取0.3--0.5ml适宜的液体培养基,滴入安瓿管内,轻轻振荡,使冻干菌体溶解呈悬浮状。吸取全部菌体悬浮液,移植于1-2支建议的培养基试管中,并在建议的条件下培养。
3、注意事项:菌种活化前,请将安瓿管保存在6-10℃的环境下,某些菌种经过冷冻干燥保存后,延迟期较长,需要连续两次继代培养才能正常生长。
4、复苏后的菌种在传1-2代后使用。
5、暂不启开的安瓿及复苏后需保藏的斜面应于4℃中保藏。
特别注意事项
l、微生物菌种应保藏于低温、清洁和干燥的地方,室温放置时问过长会导致菌种衰退;
2、菌种操作应在无菌条件下进行,防止杂菌污染:
3、斜面菌种保藏时间通常为1-2个月,应根据菌种状况及时转接;冻干菌种保藏时间通常为5~10年;
4、菌种使用过程中如出现杂菌污染或菌种生产性能下降,应及时与中国微生物菌种查询网联系或更换新的菌种。

  西林瓶和甘油冻存管打管说明
 
二、西林瓶菌种打管复活操作步骤
1、用 75%酒精棉擦拭西林瓶表面进行消毒。 
2、在生物安全柜中打开铝制瓶盖和胶盖。 
3、用无菌吸管吸取 0.5ml 左右液体培养基(《菌种说明书》中固体培养基去掉琼脂即可)于西 林瓶中将冻干菌粉全部溶解。 
4、将溶解后的菌悬液转移至盛有 4~5mL 液体培养基的试管中混匀,可将残留在吸管中的 1-2 滴菌悬液转接至固体培养基上。
5、将液体试管和斜面试管于推荐条件下静置培养,以液体培养结果为准。
三、甘油冻存管菌种打管复活操作步骤 
1、准备好推荐的菌种培养基(见《菌种说明书》)。
2、将冻存管下半部浸入 37℃温水中轻轻摇动,使冷冻状态的菌种悬液迅速融化。如果收到菌 种冻存管时菌悬液是融化状态则需要立即进行转接培养。 3、用 75%酒精棉擦拭冻存管表面进行消毒。
4、在生物安全柜中打开冻存管瓶盖,用无菌吸管吸取全部菌悬液,均匀涂布到 2 支试管斜面 或平板上。 
5、将斜面试管或平板于推荐条件下静置培养。对于生长缓慢的菌种应持续培养 2 周至更长的 时间。
四、注意事项 
1、 所有打管操作都需要无菌操作。需由专业微生物技术人员在相应防护设备中进行,生物危 害程度为三类的菌种应在生物安全柜中操作。 
2、 西林瓶和冻存管打开后需一次用完,不能留存。 
3、 菌种经过冻干保藏后,处于休眠状态,需要转接 2-3 代恢复活力。
4、 大部分冻干菌种会在培养几天后生长。有些菌种第一代恢复生长时会有较长的延迟期,培养此类菌种时需要将培养时间延长至正常培养时间的双倍时长,甚至 2 周至更长的时间。
