01General information

Description

EL4 细胞系源自小鼠淋巴瘤,被广泛用于免疫学和癌症研究。这些细胞来源于胸腺瘤(一种由胸腺上皮细胞产生的肿瘤),是研究 T 细胞淋巴瘤和免疫反应的模型。EL4 细胞对于研究 T 细胞的发育、活化和信号传导机制以及肿瘤细胞与免疫系统之间的相互作用非常有价值。由于其淋巴来源,EL4 细胞还可用于研究细胞因子的产生和功能,细胞因子对免疫调节至关重要。

EL4 细胞显示淋巴细胞形态,并表达 T 细胞的特征标记,如 CD3 和 T 细胞受体复合物。它们对激活 T 细胞的各种刺激反应灵敏,因此适合研究 T 细胞受体信号通路和免疫调节药物的作用。此外,EL4 细胞还可用于肿瘤免疫学研究,探索癌细胞与免疫系统之间的相互作用,帮助开发治疗 T 细胞淋巴瘤和其他癌症的免疫疗法。EL4细胞能产生大量特定的细胞因子,如白细胞介素-2(IL-2),这使它们成为基础研究和开发针对免疫反应的治疗策略的有用工具。

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
Subculturing
悬浮细胞:用新鲜培养基移取基质中的细胞。若要获得单细胞,可将悬浮液通过 22 号针头数次,然后分装到新的烧瓶中。在胶原上生长:要移除粘附的细胞,请使用以下标准方案。去除培养基,用不含钙和镁的 PBS 冲洗附着细胞(T25 细胞培养瓶用 3-5 毫升 PBS,T75 细胞培养瓶用 5-10 毫升)。加入 TrypleExpress(每个 T25 细胞培养瓶 1-2 毫升,每个 T75 细胞培养瓶 2.5 毫升),细胞片必须完全覆盖。在 37 摄氏度下培养 10 分钟。小心重悬细胞,可选择添加培养基,但不是必须的,然后分装到装有新鲜培养基的新培养瓶中。
Fluid renewal
每周 2 至 3 次
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。
