01General information

Description

达乌迪细胞系是 1967 年从一名被诊断患有伯基特淋巴瘤(一种淋巴瘤)的 16 岁非洲男孩身上提取的。达乌迪细胞系以其来源患者的名字命名,其特点是 Epstein-Barr 病毒(EBV)阳性,这是 Burkitt 淋巴瘤和其他几种淋巴增生性疾病的共同特征。这些细胞内的 EBV 感染为研究病毒在肿瘤发生中的作用,尤其是在 B 细胞恶性肿瘤中的作用提供了一个独特的模型。

Daudi 人体细胞表面缺乏经典的主要组织相容性复合物(MHC)I 类分子的表达,这是由于缺乏 beta-2-微球蛋白,而这种蛋白是负责 MHC I 类分子在细胞内正确折叠和在内质网中处理的关键成分。Daudi 细胞系中缺乏 beta-2-微球蛋白会导致细胞表面缺乏适当表达这些分子所需的糖基修饰。

Daudi 细胞系被广泛用于免疫学研究,尤其是涉及淋巴细胞亚群(包括淋巴细胞、自然杀伤细胞和外周血单核细胞)免疫耗竭的研究。

总之,Daudi 细胞系是促进我们在从细胞生物学的基本认识到开发癌症治疗的靶向疗法等各个研究领域的知识的重要资源。

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。

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.

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。
