01General information
- Description
NU-DUL-1 是一种源自成年患者的人源性弥漫性大B细胞淋巴瘤(DLBCL)细胞系。该细胞系因其在研究非霍奇金淋巴瘤(尤其是侵袭性弥漫性大B细胞亚型)的分子和细胞机制方面的应用价值而备受关注。 NU-DUL-1 细胞表现出 DLBCL 的典型特征,包括 B 细胞分化异常和信号传导通路失调,使其成为淋巴瘤研究中一个相关的体外模型。
NU-DUL-1细胞呈悬浮生长,具有淋巴母细胞样细胞典型的圆形单细胞形态。它们携带与弥漫性大B细胞淋巴瘤密切相关的遗传异常,为研究致癌信号通路、耐药机制及潜在治疗靶点提供了重要工具。 研究人员常利用 NU-DUL-1 细胞来研究化疗药物和单克隆抗体的疗效,以及对靶向治疗的分子反应。
该细胞系非常适合用于肿瘤免疫学研究,因为它保留了与免疫逃逸及与肿瘤微环境相互作用相关的特征。NU-DUL-1细胞系为临床前研究提供了一个强大的平台,有助于深入了解弥漫性大B细胞淋巴瘤(DLBCL)的生物学特性,并为开发针对这种侵袭性淋巴瘤亚型的新型治疗策略做出贡献。

06Handling 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
- Fluid renewal
- 每周 2 至 3 次
- 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.
07Quality 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。

09Legal 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。
