BioLife Solutions CryoStor® Usage and Cryopreservation Protocol使用與凍存方法
CryoStor使用說(shuō)明書(shū)
準(zhǔn)備細(xì)胞
1. 待冷凍細(xì)胞配制懸液(機(jī)械法或酶法解離)。
2. 細(xì)胞懸液離心獲得沉淀。
3. 去除上清液 - 注意:盡可能多地移除培養(yǎng)基,以降低CryoStor®凍存液被稀釋程度。
細(xì)胞凍存
4. 分離:加入預(yù)冷的(2-8°C)CryoStor®凍存液。
a. 細(xì)胞密度:0.5-10×106 細(xì)胞/ mL,常規(guī)細(xì)胞培養(yǎng)方案(細(xì)胞密度可以更高)。
b. CryoStor®凍存液已經(jīng)混合了DMSO,不需要再添加其他任何凍存劑。
5. 預(yù)冷:細(xì)胞/CryoStor®混合懸液2-8°C孵育約10分鐘。
6. 成核:-70°C冷凍樣品(許多方案交替使用-70°C和-80°C)
a. 大多數(shù)哺乳動(dòng)物細(xì)胞,使用程序降溫法 (-1°C/min)或類(lèi)似方法。
b. 程序降溫盒或異丙醇容器需要預(yù)冷到 2-8°C。
c. 約-5℃時(shí) (-70°C冷凍約15-20min后)啟動(dòng)樣品內(nèi)的冰核形成(seeding),啟動(dòng)方法可以是程序降溫儀控制的液氮噴放或是機(jī)械攪拌樣本(輕彈或輕拍)。
d. 使用異丙醇容器的冷凍時(shí)間(-70°C)建議為3-4小時(shí)。
保存樣本
7.樣本保存
a. 長(zhǎng)時(shí)保存溫度液氮-130°C以下。
b. -80°C 保存建議只能用于短時(shí)期保存,幾周到幾月。
樣本解凍
8. 解凍復(fù)蘇:37°C水浴快速解凍樣本。
a. 解凍時(shí)輕輕搖晃,直到看不到任何冰塊。1mL凍存管樣本解凍時(shí)間大約3分鐘。
b. 樣本不能在結(jié)冰點(diǎn)以上加熱(0-10°C)。水浴中拿出來(lái)時(shí),凍存管觸感是冷的。不推薦被動(dòng)解凍。
9. 立即用培養(yǎng)基稀釋細(xì)胞/CryoStor®混合物。
a. 稀釋步驟可以一步完成。
b. 稀釋用培養(yǎng)基溫度為20°C到 37°C。
c. 推薦稀釋比例≥1:10 (樣本:培養(yǎng)基)
10.合適的條件下培養(yǎng)細(xì)胞。
11. 使細(xì)胞進(jìn)入培養(yǎng)環(huán)境或立即使用細(xì)胞。
12. 解凍后24h進(jìn)行細(xì)胞活力檢測(cè)。*
注意:細(xì)胞活力檢測(cè)應(yīng)該在解凍后24h進(jìn)行,以保證結(jié)果準(zhǔn)確,并且以非冷凍樣本作為對(duì)照。
*解凍后立即使用細(xì)胞膜完整性指示劑進(jìn)行樣本檢測(cè),如臺(tái)盼藍(lán),分析樣本細(xì)胞產(chǎn)量和活力,結(jié)果一般會(huì)高于正常值。
推薦使用更準(zhǔn)確的活力檢測(cè)方法,活死細(xì)胞熒光分析或代謝分析(MTT or alamarBlue®)。
同時(shí)推薦視覺(jué)觀察方法,細(xì)胞貼壁和“漂浮”情況。

CryoStor凍存液英文原版說(shuō)明書(shū)
細(xì)胞準(zhǔn)備
1) 細(xì)胞重懸Place cells to be cryopreserved into suspension (mechanical or enzymatic dissociation)
2) 細(xì)胞離心Centrifuge cells to obtain cell pellet
3) 去上清液Remove supernatant - Note: Remove as much culture media as possible, to reduce dilution of CryoStor® solution.
加BioLife Solutions CryoStor CS10凍存液
4) ISOLATION: Add cold (2-8°C) CryoStor®
a. 細(xì)胞密度Cell concentrations: 0.5-10 x 106cells/ml for routine cell culture protocols (higher [cell] possible).
b. CryoStor CS10凍存液已經(jīng)預(yù)混入DMSO。DMSO is pre-mixed in CryoStor® - no additives are necessary.
5) 凍存前冷孵育PRE-FREEZE: Incubate cell suspension at 2-8°C for approximay 10 minutes
6) NUCLEATION: Freeze samples at -70°C (many protocols utlilize -70°C and -80°C interchangeably)
a.程序降溫 Use a controlled rate freeze (-1°C/min) or similar protocol for most mammalian cell systems.
b. The freezing device or isopropanol container should be pre-cooled to 2-8°C.
c. Ice nucleation within the sample (seeding) should be initiated at approximay -5°C using either a liquid nitrogen burst program setting on a controlled rate freezer or mechanical agitation (flick or tap) of the cryovial/sample container after approximay15-20 min. at -70°C.
d. Freeze time (-70°C) using isopropanol containers is recommended to be 3-4 hours.
BioLife Solutions CryoStor CS10儲(chǔ)存
7) STORAGE: Place samples into storage
a. Store samples at liquid nitrogen temperatures (below -130°C).
b. Sample storage at -80°C is only recommended for short-term storage (weeks to months).
細(xì)胞復(fù)蘇解凍
8) 水浴快速解凍THAWING: Thaw samples quickly in a 37°C water bath
a. Sample thawing should be conducted with gentle swirling of sample until all visible ice has melted. Approximate thaw time for a 1 ml sample in a cryovial is approximay 3 minutes.
b. DO NOT allow sample to warm above chilled temperatures (0-10°C). Cryovials should be cool to the touch when removed from bath.Passive thaw is not recommended.
9) 培養(yǎng)基稀釋細(xì)胞Dilute cell/CryoStor® mixture immediay with culture media
a. Dilution procedure can be preformed in a single step.
b. The dilution media should be between 20°C and 37°C.
c. A dilution ratio of 1:10 (sample to media) or greater is recommended.
10) Plate cells in appropriate configuration
11) 細(xì)胞培養(yǎng)Place cells into culture conditions or utilize immediay
12) 復(fù)蘇后細(xì)胞活力檢測(cè)Viability assessment 24-hours post-thaw*
Note: To obtain an accurate measure of cell viability following cryopreservation, assessment should be performed 24 hours post-thaw and compared to non-frozen controls.
*Sample assessment immediay post-thaw with membrane integrity indicators, such as Trypan Blue, for comparative analysis of sample cell yield and viability often results in significant overestimates of cell survival.
Live/Dead fluorescent assays or metabolic assays (MTT or alamarBlue®) are recommended for more accurate viability assessment.
Visual inspection of adherent cells and cells “floating” in the media is also recommended.
