培養方法

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

生長條件 37℃，5%CO2，CM1-1培養液。CM1-1培養液：90%DMEM-H+10%FBS。DMEM-H：DMEM高糖培養液，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，過夜轉移至液氮中保存。

培養操作步驟 ：

1．用蓋片鑷將蓋玻片自75%乙醇中取出，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孔培養板（每孔一片）或培養皿中（每個平皿可放置2-3片）； 

3．在距離紫外燈直射范圍內20-30 厘米處照射2-3小時； 

4．將經過計數的細胞懸浮液移入培養板中，使蓋玻片完全浸在培養液中； 

5．將培養板在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板底部2/3面積時，將培養板取出，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基終止消化；若細胞還是貼壁，放回培養箱繼續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用新鮮培養基重懸后加入培養瓶或皿中，T25培養瓶加6-8ml培養基；

⑥懸浮細胞直接離心收集，細胞沉淀重懸后分到新培養瓶中。

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培養基混勻。

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

3、細胞凍存：待細胞生長狀態良好時進行細胞凍存保種

①棄去培養上清，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小時后將凍存管轉入液氮罐儲存。

產品介紹 p53 binding protein 1 (53BP1) plays a critical role in tumor suppression and is a putative substrate of ATM kinase. Upon DNA damage, it is phosphorylated and relocalizes to the presumptive sites of damage, specifically, double strand breaks. This also suggests a role in DNA repair, maintaining genomic stability.

Function : May have a role in checkpoint signaling during mitosis. Enhances TP53-mediated transcriptional activation. Plays a role in the response to DNA damage.

Subunit : Interacts with IFI202A (By similarity). Binds to the central domain of p53/TP53. May form homooligomers. Interacts with DCLRE1C. Interacts with histone H2AFX and this requires phosphorylation of H2AFX on 'Ser-139'. Interacts with histone H4 that has been dimethylated at 'Lys-20' (H4K20me2). Has low affinity for histone H4 containing monomethylated 'Lys-20' (H4K20me1). Does not bind histone H4 containing unmethylated or trimethylated 'Lys-20' (H4K20me3). Has low affinity for histone H3 that has been dimethylated on 'Lys-79'. Has very low affinity for histone H3 that has been monomethylated on 'Lys-79' (in vitro). Does not bind unmethylated histone H3. Interacts with MUM1/EXPAND1. Interacts with CHEK2; modulates CHEK2 phosphorylation at 'Thr-68' in response to infrared. Interacts with MSL1; this interaction may be required for MSL1 DNA repair activity, but not for histone acetyltransferase activity.

Subcellular Location : Nucleus. Chromosome; centromere; kinetochore. Associated with kinetochores. Both nuclear and cytoplasmic in some cells. Recruited to sites of DNA damage, such as double stand breaks. Methylation of histone H4 at 'Lys-20' is required for efficient localization to double strand breaks.

Post-translational modifications : Asymmetrically dimethylated on Arg residues by PRMT1. Methylation is required for DNA binding.

實驗要點及說明：

1．本方法適用于貼壁細胞培養，而不適用于懸浮細胞培養，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一致的細胞，可以使用較大的培養皿，但不宜過大，以避免培養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。
