培養(yǎng)方法

傳代方法 將舊培養(yǎng)液吸除，PBS清洗兩遍后，加入6mL（/100mm皿）胰酶，在顯微鏡下觀察，期間禁止搖晃培養(yǎng)皿，細胞剛有脫落時，則吸除大部分胰酶，留約0.5mL，移至培養(yǎng)箱消化，約2min取出。傳代用12mL CM1-1培養(yǎng)液終止消化，輕輕吹打均勻細胞，后可分3~6皿培養(yǎng)；

生長條件 37℃，5%CO2，CM1-1培養(yǎng)液。CM1-1培養(yǎng)液：90%DMEM-H+10%FBS。DMEM-H：DMEM高糖培養(yǎng)液，含谷氨酰胺，含丙酮酸鈉。

存儲條件 凍存則用6mL凍存液（90%FBS+10%DMSO）終止消化，吹打均勻，分為6支凍存管，用程序降溫盒于-80℃凍存，過夜轉(zhuǎn)移至液氮中保存。

培養(yǎng)操作步驟 ：

1．用蓋片鑷將蓋玻片自75%乙醇??取出，用無菌絲綢布擦拭干凈，不要用紗布； 

2．將蓋玻片輕輕放入6孔培養(yǎng)板（每孔一片）或培養(yǎng)皿中（每個平皿可放置2-3片）； 

3．在距離紫外燈直射范圍內(nèi)20-30 厘米處照射2-3小時； 

4．將經(jīng)過計數(shù)的細胞懸浮液移入培養(yǎng)板中，使蓋玻片完全浸在培養(yǎng)液中； 

5．將培養(yǎng)板在5% CO2水浴孵箱中37℃孵育2-3天，當貼壁細胞生長至覆蓋培養(yǎng)板底部2/3面積時，將培養(yǎng)板取出，用蓋片鑷輕輕取出蓋玻片，用蒸餾水漂洗后即可進行快速固定以及細胞化學檢測。 

細胞培養(yǎng)方法：

1、細胞傳代：細胞密度達到80-90%時即可傳代

①棄去培養(yǎng)上清，用PBS或生理鹽水清洗1-2次；

②加入2ml0.25%胰酶（T25瓶），使胰酶覆蓋整個瓶或皿，蓋好放入培養(yǎng)箱消化；

③1-2min后，顯微鏡下觀察細胞，若大部分細胞回縮且有少量細胞脫落，輕輕吹打下確認消化情況后加入完全培養(yǎng)基終止消化；若細胞還是貼壁，放回培養(yǎng)箱繼續(xù)消化至可以輕輕吹打下為止；

④將細胞懸液1000RPM左右條件下離心4min，棄上清；

⑤用新鮮培養(yǎng)基重懸后加入培養(yǎng)瓶或皿中，T25培養(yǎng)瓶加6-8ml培養(yǎng)基；

⑥懸浮細胞直接離心收集，細胞沉淀重懸后分到新培養(yǎng)瓶中。

2、細胞復蘇：

①將凍存管在37℃溫水中快速搖晃融化，時間1min左右，加入4-5ml培養(yǎng)基混勻。

②在1000RPM左右條件下離心4min，棄上清,加1-2ml培養(yǎng)基吹勻，將細胞懸液加入培養(yǎng)瓶中，補加適量培養(yǎng)基。

3、細胞凍存：待細胞生長狀態(tài)良好時進行細胞凍存保種

①棄去培養(yǎng)上清，用PBS或生理鹽水清洗1-2次，加入1mL 0.25%胰蛋白酶（T25瓶）

②1-2min后，顯微鏡下觀察細胞，大部分細胞回縮且有少量細胞脫落，輕輕吹打下確認消化情況后加入完全培養(yǎng)基終止消化；

③將細胞懸液1000RPM左右條件下離心4min，棄上清，加1ml凍存液重懸細胞；

④將凍存管放入程序降溫盒，放入-80℃冰箱，4小時后將凍存管轉(zhuǎn)入液氮罐儲存。

產(chǎn)品介紹 This gene product is highly similar to Schizosaccharomyces pombe rad9, a cell cycle checkpoint protein required for cell cycle arrest and DNA damage repair in response to DNA damage. This protein is found to possess 3' to 5' exonuclease activity, which may contribute to its role in sensing and repairing DNA damage. It forms a checkpoint protein complex with RAD1 and HUS1. This complex is recruited by checkpoint protein RAD17 to the sites of DNA damage, which is thought to be important for triggering the checkpoint-signaling cascade. Use of alternative polyA sites has been noted for this gene. [provided by RefSeq].

Function : Component of the 9-1-1 cell-cycle checkpoint response complex that plays a major role in DNA repair. The 9-1-1 complex is recruited to DNA lesion upon damage by the RAD17-replication factor C (RFC) clamp loader complex. Acts then as a sliding clamp platform on DNA for several proteins involved in long-patch base excision repair (LP-BER). The 9-1-1 complex stimulates DNA polymerase beta (POLB) activity by increasing its affinity for the 3'-OH end of the primer-template and stabilizes POLB to those sites where LP-BER proceeds; endonuclease FEN1 cleavage activity on substrates with double, nick, or gap flaps of distinct sequences and lengths; and DNA ligase I (LIG1) on long-patch base excision repair substrates. The 9-1-1 complex is necessary for the recruitment of RHNO1 to sites of double-stranded breaks (DSB) occurring during the S phase. RAD9A possesses 3'->5' double stranded DNA exonuclease activity. Its phosphorylation by PRKCD may be required for the formation of the 9-1-1 complex.

Subunit : Component of the toroidal 9-1-1 (RAD9-RAD1-HUS1) complex, composed of RAD9A, RAD1 and HUS1. The 9-1-1 complex associates with LIG1, POLB, FEN1, RAD17, HDAC1, RPA1 and RPA2. The 9-1-1 complex associates with the RAD17-RFC complex. RAD9A interacts with BCL2L1, FEN1, PRKCD, RAD9B, HUS1, RAD1, ABL1, RPA1, ATAD5 and RPA2. Interacts with DNAJC7 and RHNO1.

Subcellular Location : Nucleus.

Post-translational modifications : Constitutively phosphorylated on serine and threonine amino acids in absence of DNA damage. Hyperphosphorylated by PRKCD and ABL1 upon DNA damage. Its phosphorylation by PRKCD may be required for the formation of the 9-1-1 complex.

Similarity : Belongs to the rad9 family.

Rad9由391個AA構成，Rad9有很多重要生物學功能，如：可調(diào)控DNA損傷反應、調(diào)節(jié)細胞的周期、對損傷的DNA進行修復、誘導細胞凋亡、調(diào)控部分基因的轉(zhuǎn)錄、具有3’端到5’端核酸外切酵素(exonuclease)的活性、促進核糖核酸的生合成以及參與胚胎發(fā)育過程。曾有報道指出Rad9在調(diào)節(jié)細胞周期、誘導細胞凋亡及維持整個基因體的完整性等方面的生物功能都和p53極為相似，因此Rad9及p53這兩種蛋白在功能上可能具有相互協(xié)調(diào)作用。

實驗要點及說明：

1．本方法適用于貼壁細胞培養(yǎng)，而不適用于懸浮細胞培養(yǎng)，懸浮細胞可使用滴片法； 

2．所使用的蓋玻片應該為玻璃**，并經(jīng)過鉻酸洗液處理； 

3．蓋玻片非常薄，易碎，取放蓋玻片時動作要輕； 

4．如果需要更多生長狀態(tài)一致的細胞，可以使用較大的培養(yǎng)皿，但不宜過大，以避免培養(yǎng)液的浪費和增加污染機率； 

5．如果細胞貼壁生長能力較差，可將蓋玻片在0.5%多聚賴氨酸溶液中浸泡5-10分鐘并自然晾干。
