【Complete Growth Medium*培養(yǎng)基】 The base medium for this cell line is DMEM/RPMI-1640 Medium. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%. 
【Subculturing傳代方法】 
Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
Remove and discard culture medium.
Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
Add 2.0 to 3.0 mL of Trypsin-EDTA solution to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
Add appropriate aliquots of the cell suspension to new culture vessels.
Incubate cultures at 37°C.
Subc*tion Ratio: A subc*tion ratio of 1:2 to 1:6 is recommended
Medium Renewal: 2 to 3 times per week

A549/DDP-LUC人肺腺癌順鉑耐藥株-熒光素酶標(biāo)記 處理方法

· 細(xì)胞名稱   A549/DDP-LUC人肺腺癌順鉑耐藥株-熒光素酶標(biāo)記

· 組織  人肺腺癌順鉑耐藥株

· 轉(zhuǎn)染方法與標(biāo)記過程的描述 慢病毒轉(zhuǎn)染Hygromycin篩選 

1. 質(zhì)粒部分

1.酶切載體：pGL4.10（luc2）由酶切獲得1400bp的luc2基因片斷；EGFP和mCherry片段由PCR擴(kuò)增獲得700-800bp左右片段；pSin-hyg-T2A載體酶切線性化。

2.電泳和膠回收：上述酶切產(chǎn)物DNA電泳，TAKARA試劑盒膠回收，回收產(chǎn)物取少量電泳鑒定。

3.連接載體與目的片段:使用Invitrogen T4連接酶連接luc2、EGFP或mCherry片段和pSin-hyg-T2A線性化載體，連接使用20ul體系，25℃，10min。

4.轉(zhuǎn)化：感受態(tài)菌One Shot Stbl3在冰上融化后，加入連接產(chǎn)物，靜置25min后在水浴42℃，45sec熱休克，后加入250ul無抗培養(yǎng)基225轉(zhuǎn)搖菌1h，將轉(zhuǎn)化的菌鋪于有氨芐抗性平板37度過夜。

5.挑取單克?。河^察平板后挑取15個單克隆至含2ml氨芐抗性 LB培養(yǎng)基搖菌管中，255轉(zhuǎn)搖菌6.5h。

6.小抽質(zhì)粒與鑒定：使用堿裂解法小抽，質(zhì)粒用25ul含RNA酶ddH2O溶解；酶切鑒定: 重組質(zhì)粒用通過酶切鑒定。

7.熒光素表達(dá)鑒定: 重組質(zhì)粒pSin-hyg-GFP/luc2（以下簡稱Gluc）或pSin-hyg-mCherry/luc2（以下簡稱Mluc） 轉(zhuǎn)染293T細(xì)胞：DNA定量后，使用PEI轉(zhuǎn)染Gluc或Mluc至24孔板已預(yù)鋪的293T細(xì)胞中。轉(zhuǎn)染采用脂質(zhì)體法轉(zhuǎn)染，試劑采用JetPEI (Polyplus公司)。兩管EP管中分別加入50ul生理鹽水，其中一管加入1ug量的質(zhì)粒（DNA體積=1ug/DNA濃度），輕輕震蕩混勻，再輕微離心；在另一管中加入PEI 2ul輕輕震蕩混勻，輕微離心，然后把PEI管中的溶液加入含有的質(zhì)粒管中，室溫孵育20min。將脂質(zhì)體包繞DNA的混合液加入需要轉(zhuǎn)染的24孔內(nèi)，37 ℃、5 % CO2條件下培養(yǎng)，8小時后換培養(yǎng)液。

8.報告基因檢測：Passive Lysis Agent裂解細(xì)胞，加入熒光素酶作用底物，將轉(zhuǎn)染質(zhì)粒的細(xì)胞與陰性，陽性對照共同進(jìn)行單報告基因檢測。

9.質(zhì)粒中抽：取1ml轉(zhuǎn)染報告基因檢測正確的菌液加入100ml氨芐抗性的LB培養(yǎng)基中搖菌過夜，使用Invitrogen試劑盒中抽，產(chǎn)物電泳鑒定，－20℃保存。
