01General information

Description

COLO-205 细胞系是一种人类结直肠腺癌细胞系,最初是从一名 70 岁的高加索男性腹水转移部位建立的。该细胞系以上皮细胞形态为特征,常用于以结直肠癌为重点的生物医学研究,特别是与癌症生物学、药物反应和转移机制有关的研究。COLO-205 细胞具有高二倍体核型,异种移植到免疫缺陷小鼠体内可形成中度分化腺癌。

COLO-205 细胞表达几种关键的致癌和抑瘤通路,因此是药理测试和癌症研究的重要模型。它们对肿瘤坏死因子相关凋亡诱导配体(TRAIL)有反应,因此适合进行凋亡研究。此外,这些细胞还被广泛用于研究各种化疗药物的药效学,为了解结直肠癌治疗的作用机制和耐药性提供了帮助。利用 COLO-205 株系进行的研究为了解结直肠腺癌的典型生物学行为(包括细胞增殖、分化以及与抗癌药物的相互作用)做出了重大贡献。

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
Subculturing
用 15 毫升试管收集悬浮细胞,用不含钙和镁的 PBS(T25 细胞培养皿用 3-5 毫升 PBS,T75 细胞培养皿用 5-10 毫升)仔细冲洗粘附的细胞。加入 Accutase(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。在环境温度下孵育 10 分钟,然后将悬浮生长的细胞和粘附的细胞一起离心。小心重悬细胞并将其分装到装有新鲜培养基的新培养瓶中。
Seeding density
1 × 10⁴ 个细胞/平方厘米
Fluid renewal
每周 2 至 3 次
Post-thaw recovery
解冻后,将细胞以5×10⁴个细胞/平方厘米的密度接种于培养皿中,使细胞从冷冻过程中恢复并至少贴壁24小时。
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。
