01General information

Description

SNU-1 细胞系来源于人类成年人的胃癌,被广泛用于胃癌研究。这种细胞系为研究胃腺癌(一种常见的致命胃癌)的分子和细胞机制提供了一个重要模型。SNU-1 细胞对于研究胃癌发病机制中涉及的基因改变和信号通路,以及开发和测试新的治疗策略尤为重要。

SNU-1 细胞呈现上皮形态,表达胃上皮细胞和腺癌的典型标志物,如癌胚抗原(CEA)和细胞角蛋白。它们经常被用于探索癌基因、肿瘤抑制基因和其他分子因素在胃癌发展中的作用的研究中。研究人员利用 SNU-1 细胞评估化疗药物、靶向疗法和综合疗法的疗效和作用机制。此外,SNU-1 细胞还是了解肿瘤微环境以及癌细胞与基质细胞之间相互作用的模型。SNU-1 细胞系与胃癌研究的相关性凸显了它在增进我们对这种恶性肿瘤的了解以及为胃癌患者开发有效治疗方法方面的重要性。

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
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
0.3-1 × 10⁶ 细胞/毫升
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。
