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。
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 Osteocalcin belongs to the osteocalcin/matrix Gla protein family and constitutes 1 to 2% of the total bone protein. It is a 49 amino acid single chain vitamin K dependent protein, made by osteoblasts, and is a major component of the noncollagenous bone matrix. Post translational modification by a vitamin K dependent carboxylase produces three gamma carboxyglutamic acid residues at positions 17, 21 and 24, giving it a high affinity for calcium. It also binds strongly to apatite.
Function : Constitutes 1-2% of the total bone protein. It binds strongly to apatite and calcium.
Subcellular Location : Secreted.
Post-translational modifications : Gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation. These residues are essential for the binding of calcium.
Similarity : Belongs to the osteocalcin/matrix Gla protein family.
Contains 1 Gla (gamma-carboxy-glutamate) domain.

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。
