01General information

Description

NS0 是一种小鼠骨髓瘤细胞系,来源于小鼠浆细胞瘤的无分泌变体。它广泛应用于生物技术和制药业,用于生产重组单克隆抗体和其他治疗蛋白。NS0 细胞适合悬浮培养,可在无血清、化学定义培养基中生长,因此非常适合在现行良好生产规范(cGMP)条件下进行大规模生物处理。它们以转染效率高和蛋白质表达产量高而著称,尤其是与强哺乳动物表达载体和扩增系统(如基于甲氨蝶呤(MTX)选择的系统)结合使用时。

尽管 NS0 细胞在蛋白质生产中很有用,但它们源自鼠类,这就带来了一些限制,包括表达的蛋白质存在非人类糖基化模式。这些差异会影响免疫原性和药代动力学,这是临床应用中需要考虑的问题。尽管如此,NS0 衍生的产品已获得监管部门的批准,并已投入临床使用,这凸显了该品系的稳健性和可扩展性。NS0 细胞不致癌,缺乏内源性免疫球蛋白表达,降低了重组抗体生产工作流程中污染原生抗体序列的风险。

05Handling and culture

Culture medium
RPMI 1640,w:2.0 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
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。
