培养方法
传代方法 将旧培养液吸除，PBS清洗两遍后，加入6mL（/100mm皿）胰酶，在显微镜下观察，期间禁止摇晃培养皿，细胞刚有脱落时，则吸除大部分胰酶，留约0.5mL，移至培养箱消化，约2min取出。传代用12mL CM1-1培养液终止消化，轻轻吹打均匀细胞，后可分3~6皿培养；
生长条件 37℃，5%CO2，CM1-1培养液。CM1-1培养液：90%DMEM-H+10%FBS。DMEM-H：DMEM高糖培养液，含谷氨酰胺，含丙酮酸钠。
存储条件 冻存则用6mL冻存液（90%FBS+10%DMSO）终止消化，吹打均匀，分为6支冻存管，用程序降温盒于-80℃冻存，过夜转移至液氮中保存。
培养操作步骤 ：
1．用盖片镊将盖玻片自75%乙醇中取出，用无菌丝绸布擦拭干净，不要用纱布；
2．将盖玻片轻轻放入6孔培养板（每孔一片）或培养皿中（每个平皿可放置2-3片）；
3．在距离紫外灯直射范围内20-30 厘米处照射2-3小时；
4．将经过计数的细胞悬浮液移入培养板中，使盖玻片完全浸在培养液中；
5．将培养板在5% CO2水浴孵箱中37℃孵育2-3天，当贴壁细胞生长至覆盖培养板底部2/3面积时，将培养板取出，用盖片镊轻轻取出盖玻片，用蒸馏水漂洗后即可进行快速固定以及细胞化学检测。
实验要点及说明：
1．本方法适用于贴壁细胞培养，而不适用于悬浮细胞培养，悬浮细胞可使用滴片法；
2．所使用的盖玻片应该为玻璃**，并经过铬酸洗液处理；
3．盖玻片非常薄，易碎，取放盖玻片时动作要轻；
4．如果需要更多生长状态一致的细胞，可以使用较大的培养皿，但不宜过大，以避免培养液的浪费和增加污染机率；
5．如果细胞贴壁生长能力较差，可将盖玻片在0.5%多聚赖氨酸溶液中浸泡5-10分钟并自然晾干。
细胞培养方法：
1、细胞传代：细胞密度达到80-90%时即可传代
①弃去培养上清，用PBS或生理盐水清洗1-2次；
②加入2ml0.25%胰酶（T25瓶），使胰酶覆盖整个瓶或皿，盖好放入培养箱消化；
③1-2min后，显微镜下观察细胞，若大部分细胞回缩且有少量细胞脱落，轻轻吹打下确认消化情况后加入完全培养基终止消化；若细胞还是贴壁，放回培养箱继续消化至可以轻轻吹打下为止；
④将细胞悬液1000RPM左右条件下离心4min，弃上清；
⑤用新鲜培养基重悬后加入培养瓶或皿中，T25培养瓶加6-8ml培养基；
⑥悬浮细胞直接离心收集，细胞沉淀重悬后分到新培养瓶中。
2、细胞复苏：
①将冻存管在37℃温水中快速摇晃融化，时间1min左右，加入4-5ml培养基混匀。
②在1000RPM左右条件下离心4min，弃上清,加1-2ml培养基吹匀，将细胞悬液加入培养瓶中，补加适量培养基。
3、细胞冻存：待细胞生长状态良好时进行细胞冻存保种
①弃去培养上清，用PBS或生理盐水清洗1-2次，加入1mL 0.25%胰蛋白酶（T25瓶）
②1-2min后，显微镜下观察细胞，大部分细胞回缩且有少量细胞脱落，轻轻吹打下确认消化情况后加入完全培养基终止消化；
③将细胞悬液1000RPM左右条件下离心4min，弃上清，加1ml冻存液重悬细胞；
④将冻存管放入程序降温盒，放入-80℃冰箱，4小时后将冻存管转入液氮罐储存。

产品介绍 Expression of the POU-domain transcription factor Octamer-4 (Oct-4) is widely regarded as a hallmark of pluripotent stem cells. The relationship of Oct-4 to pluripotent stem cells is indicated by its tightly restricted expression to undifferentiated pluripotent stem cells. Upon differentiation to somatic lineages, the expression of Oct-4 disappears rapidly. Unlike the majority of pluripotent stem cell markers, the biological role of Oct-4 has been well characterized. Studies performed in mice point to the critical role of Oct-4 in the establishment and/or maintenance of pluripotent stem cells in an uncommitted state.
Function : Transcription factor that binds to the octamer motif (5'-ATTTGCAT-3'). Forms a trimeric complex with SOX2 on DNA and controls the expression of a number of genes involved in embryonic development such as YES1, FGF4, UTF1 and ZFP206. Critical for early embryogenesis and for embryonic stem cell pluripotency.
Subunit : Interacts with UBE2I and ZSCAN10 (By similarity). Interacts with PKM2. Interacts with WWP2.
Subcellular Location : Cytoplasm. Nucleus. Note=Expressed in a diffuse and slightly punctuate pattern.
Tissue Specificity : Expressed in developing brain. Highest levels found in specific cell layers of the cortex, the olfactory bulb, the hippocampus and the cerebellum. Low levels of expression in ***** tissues.
Post-translational modifications : Sumoylation enhances the protein stability, DNA binding and transactivation activity. Sumoylation is required for enhanced YES1 expression (By similarity).
Ubiquitinated; undergoes 'Lys-63'-linked polyubiquitination by WWP2 leading to proteasomal degradation (By similarity).
ERK1/2-mediated phosphorylation at Ser-111 promotes nuclear exclusion and proteasomal degradation. Phosphorylation at Thr-235 and Ser-236 decrease DNA-binding and alters ability to activate transcription.
