01General information

Description

A427 细胞来源于肺组织,特别是癌细胞,呈上皮形态,可粘附生长。A427 细胞在补充了 10%胎牛血清(FBS)的 RPMI 1640 培养基中的倍增时间约为 28 小时。

在 ACL-3 培养基中,倍增时间略微延长至 38 小时,而在添加了牛血清白蛋白(BSA)的 ACL-3 培养基中,倍增时间则达到 42 小时。这些倍增时间的变化为了解细胞在不同实验条件下的行为提供了宝贵的信息。

A427 细胞在 60 代时显示出低三倍体到高三倍体的核型。这意味着细胞具有异常染色体,包括双中心染色体、分钟染色体和一个大的亚中心标记。这种核型异常通常与癌细胞有关,也是这种细胞系的独特之处。A427 细胞具有致瘤特性,注射到裸鼠体内可形成肿瘤。

这些肿瘤类似于未分化腺癌,进一步突出了该细胞系在研究肺癌及其进展方面的重要性。A427 细胞具有独特的特征,可用于各种用途,尤其是癌症研究。A427细胞的上皮形态和肺部来源使其成为研究肺癌和相关疾病的理想模型。此外,A427 细胞非常适合三维细胞培养技术,为探索肺癌细胞的行为提供了更贴近生理的环境。

Culture medium
EMEM(MEM Eagle),w:2 mM L-谷氨酰胺,w:2.2 g/L NaHCO3,w:EBSS(Cytion 文章编号 820100a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
Dissociation reagent
Accutase
Subculturing
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。
Seeding density
1×10⁴个细胞/cm²将在3天内形成融合的单层细胞。
Fluid renewal
每周 2 至 3 次
Post-thaw recovery
解冻后,将细胞以4×10⁴个细胞/cm²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。
