01General information

Description

EB3 细胞系是一种人类伯基特淋巴瘤模型,最初来源于乌干达一名患有上颌骨肿瘤的幼儿。它是早期研究这种恶性肿瘤的免疫学和生物学特征时建立的几种成熟的伯基特淋巴瘤细胞系之一。值得注意的是,当用化疗后病情缓解的伯基特淋巴瘤患者的血清进行检测时,EB3 细胞表现出很强的膜免疫荧光反应性,表明其表面存在肿瘤相关抗原。使用荧光素结合的抗 IgG 试剂显示,这种反应性可能是由 IgG 类抗体介导的。研究发现,EB3 与其他伯基特细胞系(如 Jijoye、B35M 和 SL1)反应强烈,而某些其他伯基特细胞系(如 Raji)在相同条件下没有类似反应。

早期的比较研究曾使用 EB3 细胞来区分伯基特淋巴瘤的肿瘤特异性反应和同抗原反应。这些研究表明,一些患者(尤其是完全缓解的患者)的血清可以选择性地识别伯基特淋巴瘤细胞,而不是正常骨髓或来自同一供体的淋巴细胞,这表明了肿瘤特异性免疫原标志物。此外,EB3 细胞显示的形态和免疫表型特征与大淋巴母细胞样伯基特淋巴瘤细胞一致,后者暴露于反应性血清时往往表现出明亮的颗粒膜染色。对 EB3 进行这一历史性的免疫学分析,有助于为后来探索淋巴恶性肿瘤特异性抗原的研究奠定基础。

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% 热灭活 FBS
Subculturing
通过上下吸取操作轻柔匀化烧瓶中的细胞悬液,随后取代表性样本测定每毫升细胞密度。用新鲜培养基将悬液稀释至1×10⁵细胞/毫升浓度,并将调整后的悬液分装至新烧瓶中进行后续培养。
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。
