01General information

Description

P388 是一种小鼠淋巴肿瘤细胞系,来源于 DBA/2 小鼠的自发性淋巴细胞白血病。它常用于癌症研究,特别是研究白血病和测试抗癌化合物。P388 细胞悬浮生长,在最佳培养条件下,倍增时间约为 24 小时。这种细胞的特点是增殖速度快,对化疗药物的敏感性高,因此是评估癌症新疗法疗效的重要工具。

P388 细胞表达典型的淋巴系标志物,包括表面免疫球蛋白和与 B 细胞相关的各种细胞表面抗原。研究人员经常在体内模型中利用这种细胞系接种小鼠,研究肿瘤的生长、转移和对疗法的反应。此外,P388 细胞系还是研究白血病分子机制(如特定致癌基因和肿瘤抑制基因的作用)的模型。

尽管 P388 细胞系被广泛使用,但它也有其局限性,比如与人类缺乏相关性,以及在长时间培养后可能出现基因漂移。因此,研究人员经常用其他模型来补充涉及 P388 细胞的研究,以获得对白血病生物学和治疗反应的全面了解。

05Handling 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。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。
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.

06Quality 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。
