详细介绍

资源编号:BNCC339366

英文名: alpha TC1 clone 6

类型: alpha cells

形态: epithelial

提供形式: T25细胞培养瓶/冻存管

安全等级: 2

应用领域: The alpha TC1 clone 6 cells are useful for studying many aspects of islet biology, including glucagon biosynthesis and cytokine sensitivity.

培养方法

培养基 90%高糖DMEM+10%FBS
传代方法 Volumes used in this protocol are for 75 cm2 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. NOTE: Warm all solutions to 37.0°C prior to use Transfer all medium and floating cells from flask to a 50 mL centrifuge tube. Adherent cells are removed using Cell Dissociation Buffer (an enzyme free buffer; Invitrogen, Catalog No. 13150-016) diluted 1:5 with Hanks' Balanced Salt Solution. Add 5.0 mL of diluted cell dissociation buffer per 75 cm2 flask and gently rock flask to bathe the cells at room temperature for 1 to 2 minutes. Allow the flask to remain at room temperature for 1 to 5 additional minutes until cells have detached from the flask. Firmly tap the flask against palm of hand to dislodge cells. Add 10.0 mL of fresh medium per 75 cm2 flask and triturate up and down directing the stream along the growth surface of the flask to dislodge the cells and break up some of the clumps. Transfer these cells to the centrifuge tube from Step 1. Centrifuge at 125 x g  for 5 to 10 minutes. Remove medium and resuspend pellet in fresh complete medium. Add appropriate aliquots of cell suspension to new culture vessels. Incubate cultures at 37°C. Subcultivation ratio: A subcultivation ratio of 1:3 to 1:4 is recommended. Medium renewal: Every 2 to 3 days.
生长条件 95%空气+5%二氧化碳 37摄氏度
生长特性 adherent, with loosely attached clusters and some single cells in suspension
存储条件 50%高糖DMEM+40%FBS+10%DMSO 液氮

贴壁,上皮细胞样

培养:37℃,5%CO2 89%DMEM-H+10%FBS +1%NEAA

编号: 339366

产品形式: 2mL 冻存管 × 2支、或 T25 × 1瓶

安全等级: 一级,安全柜或超净台操作

收货须知:收货当天发现异常,请在 24 小时内及时联系客服,逾期视为收货良好;冻存管形式,收货后及时置于-80℃冰箱保存,若 长时间不使用,应过夜转移至液氮保藏;T25 形式,收货后先培养瓶原装置于培养箱静养 4h,然后再对细胞进行常规操作。复苏时每 管一次用完不得留存,复苏后传一代,即可正常使用。请严格按照本说明操作,否则造成细胞失活等情形,不予提供补发服务。

培养条件:37℃,5%CO2,89%DMEM-H +10%FBS+1%NEAA。DMEM-H:DMEM 高糖培养液,含谷氨酰胺,含丙酮酸钠。

复苏步骤:

①新制 100mm 平皿 1个,含 12mL 上述培养液;

②冻存管从液氮或-80℃中取出,37℃水浴 1~2min,待完全溶解后尽快移入 安全柜复苏;

③用无菌吸管吸取溶解液打入新制平皿中,顺时针摇匀;

④放入(37℃,5%CO2)培养箱中,过夜换液,4-6 天长满。

传代/冻存:将旧培养液吸除,PBS 清洗两遍后,加入 2mL(/100mm 皿/T25 瓶)胰酶(0.25%Trypsin+0.02%EDTA),在显微镜下观察, 期间禁止摇晃培养皿,细胞刚有脱落时,吸除大部分胰酶,留约 0.5mL,移至培养箱消化,约 1.5min 取出。

①传代:6mL 培养液终止 消化,轻轻吹打均匀细胞,后可 1:2 传代;

②冻存:3mL 冻存液(50%基础培养基+40%FBS+10%DMSO)终止消化,吹打均匀,分为 3支 冻存管,用程序降温盒于-80℃冻存。

复苏质量记录:根据复苏要求,对以上细胞株进行复苏,记录结果如下:

项目 质量标准 复苏记录
复活性 18h贴壁,130h长满 80% 过夜 18h观察贴壁,120h密度达 80%
细胞形态 贴壁,上皮细胞样 贴壁,上皮细胞样,多角形,松散附着的簇和一些悬浮的单细胞
附图
结论  复活性好,且细胞形态无异常,合格
