【Hs888Lu人肺成纖維細胞 】下面是細胞株培養(yǎng)的具體無菌技術(shù)要點:
1. 實驗開始前,無菌室和無菌操作臺需要紫外光照射30到60分鐘完全滅菌,用70%ethanol擦拭無菌操作臺面,并且打開無菌操作臺風(fēng)扇運行10分鐘之后,才可以進行實驗操作。每次操作只能處理一株細胞株,即使培養(yǎng)基完全相同也不可共用培養(yǎng)基,以避免細胞間污染或失誤混淆。實驗完成后,請將實驗物品拿出工作臺,用70%ethanol再次擦拭無菌操作臺面。操作間隔應(yīng)該讓無菌操作臺運轉(zhuǎn)10分鐘到15分鐘后,才能進行下一個細胞株的操作。
2. 無菌操作工作的區(qū)域應(yīng)保持清潔和寬敞,必要物品(試管架、吸管、吸取器或吸管盒等)可以暫時放置,其它實驗用品使用完畢后應(yīng)移出,有利于空氣流通。實驗用品需70%ethanol擦拭后方可帶入無菌操作臺內(nèi)。實驗操作過程應(yīng)在臺面的中央無菌區(qū)域內(nèi)完成,請勿在邊緣非無菌區(qū)域進行操作。
3. 小心取用無菌實驗物品,避免細菌污染。請勿觸碰吸管尖頭部和容器瓶口處,也不要在打開的容器正上方進行操作。容器打開后,請用手夾住瓶蓋并輕握瓶身,傾斜大約45°角取用,盡量不要將瓶蓋口朝上放置于桌面。
4. 工作人員應(yīng)當首先注意自身安全,必須穿戴齊實驗衣和實驗手套后才能進行實驗。對于病毒感染或是來自人類的細胞株應(yīng)當特別小心操作,并選擇適當?shù)燃壍臒o菌操作臺進行(至少是Class II)。操作過程中,應(yīng)避免引起aerosol的產(chǎn)生,小心有毒性藥品,例如DMSO和TPA等,并避免針頭的傷害等等。
5. 定期檢測下列項目:
5.1. CO2鋼瓶的CO2壓力
5.2. CO2培養(yǎng)箱的CO2濃度、溫度、和水盤是否有污染(水盤的水需用無菌水,每周定時更換)。
5.3. 無菌操作臺內(nèi)的airflow壓力,定期更換紫外線燈管和HEPA過濾膜,預(yù)濾網(wǎng)(300小時/預(yù)濾網(wǎng),3000小時/HEPA)。
6. 水槽內(nèi)可添加消毒劑(Zephrin 1:750),需定期更換水槽中的水。

2、種屬:Homo sapiens 人
四、培養(yǎng)條件
1、培養(yǎng)基:RPMI-1640 培養(yǎng)基(不含 Hepes)+ 10%胎牛血清+ 1%雙抗
2、溫度:37.0°C
3、氣體:空氣 95%,CO2 5%
【Hs888Lu人肺成纖維細胞 】五、培養(yǎng)方法
收到細胞后,在倒置顯微鏡下觀察整個細胞生長情況:
如果細胞未長滿,用 75%酒精噴灑整個瓶消毒后放到超菌臺內(nèi),嚴格無菌操作,打開細胞培養(yǎng)瓶,留10ml 培養(yǎng)液繼續(xù)培養(yǎng)。如果細胞已長滿(達 80-90%)。即可進行傳代,具六、體步驟如下:
1,棄去培養(yǎng)液,用PBS洗 1-2次。
2,向瓶內(nèi)加入 1.0-2.0ml 胰蛋白酶液,在倒置顯微鏡下觀察細胞消化情況,若細胞大部分變圓,迅速拿回操作臺,吸取胰蛋白酶,加含有 6ml 含 10%血清的培養(yǎng)液,輕輕吹打細胞。
3,加入等量的的培養(yǎng)液,輕輕吹打混勻后吸出一半,分到新的培養(yǎng)
4,傳代比例:1:2-1:3
七、常見問題及解決方案
1、培養(yǎng)瓶有破裂,培養(yǎng)液有漏液:細胞極大可能會污染,所以我們會及時安排幫老師解決。
2、細胞漂。号囵B(yǎng)瓶不開封,瓶口酒精擦拭后平躺放置在培養(yǎng)箱。次日觀察,如細胞大部分又貼回瓶底,表明細胞活力正常,剩余漂浮的細胞可以去掉,留 10ml 培養(yǎng)液培養(yǎng)觀察,細胞生長至匯合度 80%,進行消化傳代;如細胞還是不貼壁,將細胞離心收集轉(zhuǎn)到新培養(yǎng)瓶,原培養(yǎng)瓶加部分培養(yǎng)液繼續(xù)培養(yǎng),中間注意觀察,我們的技術(shù)人員會一直跟蹤指導(dǎo),直到問題解決。
