      Medium 培養(yǎng)基 ATCC? Medium 2154: LYI Entamoeba medium

      ATCC? Medium 361: Modified TYM basal medium (ATCC medium 358) with pH adjusted to 6.0 and 0.2-0.5 ml of heat-inactivated horse serum added per tube before use

      Growth Conditions 生長(zhǎng)條件

      Temperature 培養(yǎng)溫度: 35℃

      Atmosphere 需氧情況: Microaerophilic

      Culture System: Axenic; pH 6 Cryopreservation Harvest and Preservation

      1,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.,

      2,Adjust the concentration of cells to 2 x 106 - 2 x 107/mL in fresh medium.

      3,While cells are centrifuging prepare a 10% (v/v) solution of sterile DMSO in fresh medium.,

      a,Add 1.0 mL of DMSO to an ice cold 20 x 150 mm screw-capped test tube;

      b,Place the tube on ice and allow the DMSO to solidify (~5 min) and then add 9.0 mL of ice cold medium;

      c,Invert several times to dissolve the DMSO;

      d,Allow to warm to room temperature.

      4,Mix the cell preparation and the DMSO in equal portions. Thus, the final concentration will be 106 - 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.,

      5,Dispense in 0.5 mL aliquots into 1.0 - 2.0 mL sterile plastic screw-capped cryules (special plastic vials for cryopreservation).,

      6,Place the vials in a controlled rate freezing unit.  From room temperature cool at -1℃/min to -40℃.  If the freezing unit can compensate for the heat of fusion, maintain rate at -1℃/min through the heat of fusion.  At -40℃ plunge into liquid nitrogen. Alternatively, place the vials in a Nalgene 1℃ freezing apparatus.  Place the apparatus at -80℃ for 1.5 to 2 hours and then plunge ampules into liquid nitrogen.  (The cooling rate in this apparatus is approximately -1℃/min.) 

      7,The frozen preparations should be stored in either the vapor or liquid phase of a nitrogen refrigerator. Frozen preparations stored below -130℃ are stabile indefinitely. Those stored at temperatures above -130℃ are progressively less stabile as the storage temperature is elevated. Vials should not be stored above -55℃.

      8,To establish a culture from the frozen state place an ampule in a water bath set at 35℃. Immerse the vial just to a level just above the surface of the frozen material. Do not agitate the vial.,

      9,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.

      ,10,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).

      常見(jiàn)問(wèn)題
      問(wèn):細(xì)胞的運(yùn)輸方式有哪些?有什么區(qū)別?

      答:公司提供兩種運(yùn)輸方式供老師選擇,1、復(fù)蘇的活細(xì)胞:采用常溫發(fā)貨的方式,收到即可觀察密度并判斷是否進(jìn)行傳代操作。優(yōu)勢(shì)是省去復(fù)蘇的步驟,細(xì)胞成活率較高。2、凍存的細(xì)胞:采用干冰運(yùn)輸,一般情況下發(fā)貨是2支凍存管,收到后放-80過(guò)夜,第二天轉(zhuǎn)入液氮長(zhǎng)期存儲(chǔ),擇機(jī)復(fù)蘇。優(yōu)勢(shì)是發(fā)貨快,一般一兩天即可收到,缺點(diǎn)是需要自己復(fù)蘇。

      問(wèn):為什么你們的細(xì)胞和其他公司的細(xì)胞培養(yǎng)條件不一樣?

      答:我公司提供的細(xì)胞大部分都參考資源庫(kù)的培養(yǎng)信息,如ATCC、DSMZ、中科院等等官方平臺(tái)。也有少部分細(xì)胞為客戶(hù)提供了替代培養(yǎng)方案,根據(jù)客戶(hù)的意愿進(jìn)行選擇!

      問(wèn):培養(yǎng)瓶的培養(yǎng)液可以重復(fù)使用嗎?

      答:不可以重復(fù)使用,一般從我公司發(fā)出的細(xì)胞都需要達(dá)到一定的密度后發(fā)出,充液的培養(yǎng)基血清比例會(huì)比正常培養(yǎng)時(shí)所用到的培養(yǎng)液低很多,通常在3-5%,以維持細(xì)胞存活,控制生長(zhǎng)速度,不可以用來(lái)做細(xì)胞培養(yǎng)使用。

      問(wèn):培養(yǎng)細(xì)胞在鏡下觀察發(fā)現(xiàn)有一些白色的圓點(diǎn)是什么?

      答:細(xì)胞在鏡下發(fā)現(xiàn)圓形的白色的點(diǎn)點(diǎn),一般情況下是為貼壁的細(xì)胞或脫落的細(xì)胞死亡后的產(chǎn)物,懸浮細(xì)胞也會(huì)有這種現(xiàn)象,出現(xiàn)圓形的光圈一樣的圓點(diǎn)。通常,白色的圓點(diǎn)是分散分布的,聚團(tuán)類(lèi)的懸浮細(xì)胞可能會(huì)聚團(tuán)出現(xiàn)白色的亮斑,技術(shù)老師可以繼續(xù)培養(yǎng)并觀察。

      問(wèn):剛買(mǎi)回來(lái)的細(xì)胞如何凍存留種呢?

      答:一般情況下,我公司建議客戶(hù)收到細(xì)胞后傳1-2代后即可安排凍存留種,可先凍存1-2支凍存管,凍存的細(xì)胞數(shù)量多一些,便于后期復(fù)蘇。購(gòu)買(mǎi)原代細(xì)胞的客戶(hù),要充分考慮該細(xì)胞的傳代次數(shù)限制,人源原代細(xì)胞大概可以傳7代左右,鼠源的可以傳3代左右,對(duì)于一些能傳代次數(shù)很少的原代細(xì)胞,不建議凍存,收到后調(diào)整狀態(tài)后即可安排實(shí)驗(yàn)。
