01General information

Description

NCI-H526 细胞系来源于人类成年人的小细胞肺癌(SCLC)。这种细胞系被广泛用于癌症研究,特别是小细胞肺癌的研究,小细胞肺癌以侵袭性强和预后不良而著称。NCI-H526 细胞为研究 SCLC 的生物学特性、了解其快速生长和转移以及开发新的治疗策略提供了一个重要的模型。

NCI-H526 细胞表现出小细胞肺癌特有的圆形悬浮生长形态。它们表达嗜铬粒蛋白 A 和突触素等神经内分泌标志物,这是 SCLC 的典型特征。研究人员利用 NCI-H526 细胞研究与 SCLC 相关的遗传和表观遗传学变化,包括 TP53 和 RB1 基因的改变,这些基因在这类癌症中经常发生突变。这些细胞还被用来探索驱动SCLC进展的信号通路,如Notch、PI3K/Akt和刺猬通路。在药物研发中,NCI-H526 细胞被用来评估化疗药物、靶向疗法和新型治疗组合的疗效。NCI-H526细胞系在小细胞肺癌研究中的相关性凸显了它在促进我们对这种具有挑战性的疾病的了解和开发更有效的治疗方法方面的重要性。

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。
Fluid renewal
每周 2 至 3 次
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。
