01General information

Description

NRK-52E 细胞系来源于大鼠的正常肾脏,是一种代表近端肾小管上皮细胞的上皮样细胞系。这种细胞系被广泛用于肾脏病学研究,特别是肾脏生理学、毒理学和病理生理学研究。NRK-52E 细胞显示出具有紧密连接的上皮形态特征,因此适合用于肾小管功能和屏障完整性的体外建模。

NRK-52E 细胞在研究细胞凋亡、细胞修复和离子转运机制方面发挥了重要作用。例如,该细胞系被用于研究蛋白磷酸酶抑制剂 okadaic 酸的作用,揭示了它在诱导染色质凝聚、钙离子流入和线粒体变化等凋亡途径中的作用。这些研究有助于深入了解损伤或疾病期间肾细胞死亡和存活机制的调控。

此外,NRK-52E 细胞还被用于评估各种实验装置(如模拟生理流动条件的微流体系统)下的肾上皮离子转运和屏障特性。这包括对氯化钠重吸收和跨上皮电阻的研究,这对了解肾脏生理学中的电解质和水分平衡至关重要。这些特点使 NRK-52E 成为探索肾小管细胞生物学和肾脏疾病治疗干预的可靠模型。

05Handling and culture

Culture medium
DMEM:Ham's F12(1:1),w: 3.1 g/L 葡萄糖,w: 2.5 mM L-谷氨酰胺,w: 15 mM HEPES,w: 0.5 mM 丙酮酸钠,w: 1.2 g/L NaHCO3(Cytion 文章编号 820400a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
Dissociation reagent
Accutase
Subculturing
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。
Fluid renewal
每周 2 至 3 次
Thawing and culturing
  1. Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.

  2. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required.

  3. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains.

  4. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.

  5. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently.

  6. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

06Quality control and cryopreservation

Sterility

使用基于 PCR 的检测方法和基于发光的支原体检测方法排除支原体污染。

为确保没有细菌、真菌或酵母菌污染,每天都要对细胞培养物进行目视检查。

Freeze medium
我们使用完全生长培养基(包括 FBS)+10% DMSO 或 CM-1(Cytion 商品目录编号 800100)作为冷冻保存培养基,以获得足够的解冻后存活率,CM-1(Cytion 商品目录编号 800100)含有优化的渗透保护剂和代谢稳定剂,可提高恢复能力并减少冷冻引起的应激。
Storage conditions

如需长期保存,可将样品瓶放入气相液氮中,温度约为 -150 至 -196 ℃。在-80 °C下保存只能作为转入液氮前的短暂过渡。

Shipping conditions

冷冻保存的细胞系用干冰装运,并用经过验证的隔热包装和足够的制冷剂在整个运输过程中保持约 -78 °C 的温度。收到货后,应立即检查容器,并立即将小瓶转移到适当的储藏室。
