01General information
- Description
U266 细胞系(又称 U-266)是一种人类多发性骨髓瘤细胞系,是从一名 53 岁的 IgE 骨髓瘤患者的外周血中提取的。该细胞系的特点是分泌轻型和重型免疫球蛋白链,主要是λ轻链和 IgE 重链。U266 细胞系具有典型的 B 淋巴细胞标记,已被广泛用于骨髓瘤生物学研究,特别是用于了解浆细胞恶性肿瘤的病理生理机制和免疫反应。
U266 细胞在药物发现和开发方面发挥着重要作用,为评估抗骨髓瘤药物的疗效提供了一个强大的模型。它们还用于研究骨髓瘤细胞与骨髓微环境的相互作用,这对了解骨髓瘤的发展和抗药性至关重要。遗传学研究揭示了 U266 细胞的几种染色体异常,这导致了它们的恶性表型和对凋亡的抵抗力。该细胞系对多发性骨髓瘤分子靶向疗法的发展起到了重要作用。

04Handling 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% 热灭活 FBS
- Subculturing
- 通过定期添加或更换培养基来维持细胞培养。初始培养时细胞密度应为5×10⁵个细胞/毫升,并保持细胞浓度在3×10⁵至1×10⁶个细胞/毫升范围内以获得最佳生长效果。
- Seeding density
- 5 × 10⁵ 个细胞/毫升
- Post-thaw recovery
- 解冻后,让细胞从冷冻过程中恢复至少 24 小时。
- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
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.
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.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
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.
Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.
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.
Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
05Quality 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。

07Legal and safety
- Safety precautions
- 计划将低温样品储存在液氮中以便将来解冻时,必须遵守严格的安全措施。在将冷冻样本移入或移出液氮罐时,必须穿戴适当的防护手套和防护服,并使用面罩或安全护目镜。这样做是为了降低在移出时因冷冻样品爆炸而造成伤害的风险,因为爆炸可能导致锋利的碎片飞溅。
