01General information

Description

NCI-H2444是一种人类非小细胞肺癌(NSCLC)细胞系,归类于肺腺癌谱系。 该细胞系由成人患者肺肿瘤标本建立,代表源自肺部上皮组织的恶性肿瘤。作为大规模药物基因组学及多组学特征分析项目的一部分,NCI-H2444与大量人类癌细胞系共同接受了分子特征测定,实现了基因组、转录组及药理反应数据的整合分析。

在针对数百种抗癌化合物筛选的1000余种癌细胞系的全面药物敏感性研究中,NCI-H2444等肺癌模型被用于建立致癌突变与治疗脆弱性的关联:contentReference[oaicite:0]{index=0}。这些分析整合了体细胞突变谱、拷贝数变异、DNA甲基化模式及基因表达数据,以定义具有临床意义的癌症功能事件,并将其与差异性药物反应相关联。 这些数据集使NCI-H2444能够定位于谱系特异性和突变驱动的敏感性簇群中,支持其在生物标志物发现和靶向治疗评估中的应用。

对数百种人类癌细胞系进行的蛋白质组学分析,进一步扩展了适用于NCI-H2444等模型的分子注释框架:contentReference[oaicite:1]{index=1}。 基于高分辨率质谱的数千种蛋白质定量分析,实现了蛋白质组学测量与转录组学及药理学数据集的整合。这种系统级特征分析有助于识别预测药物反应的蛋白质生物标志物,并支持在肺腺癌模型中开展通路激活、转录后调控及治疗耐药性的机制研究。

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。
