01General information

Description

Huh-7.5.1细胞系是源自Huh-7肝癌细胞的一个亚克隆,以其对丙型肝炎病毒(HCV)复制的受感性增强而著称。 作为Huh-7.5细胞系的改良版本,Huh-7.5.1细胞是从经治愈的HCV复制子细胞系中建立的,与前代细胞相比,其对HCV感染的易感性更高。 它们能够支持强劲的 HCV 复制周期,这使其成为研究 HCV 生命周期(包括病毒侵入、RNA 复制和传染性颗粒的产生)的首选模型。

由于在病毒RNA复制和传染性病毒产生方面效率更高,Huh-7.5.1细胞在HCV研究中具有特别重要的价值。 该细胞系表现出较高的病毒滴度,在感染 HCV-JFH1 株期间,培养上清液中的病毒滴度通常可达每毫升 10⁴ 至 10⁵ 个传染性单位。这一特性使得人们能够对病毒致病机制和体外抗病毒反应进行详细分析。 重要的是,Huh-7.5.1 细胞被用于筛选针对 HCV 的抗病毒化合物,这有助于开发针对 HCV 的治疗方法,并深入了解耐药机制。

此外,该细胞系还被用于更广泛的研究,涉及病毒与宿主细胞机制的相互作用、脂质代谢以及相关的治疗靶点。 例如,抑制SKI-1/S1P蛋白酶介导的SREBP通路等细胞信号通路,已被证实会影响病毒在Huh-7.5.1细胞内的复制,这凸显了该细胞系在研究宿主导向型抗病毒策略方面的实用价值。

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.

06Quality 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。
