01General information

Description

WIL2-S是一种源自外周血淋巴细胞、经爱泼斯坦-巴尔病毒(EBV)感染实现永生化的人类B淋巴母细胞样细胞系。该细胞系取自健康成人供体,具有EBV转化B细胞的典型特征,包括悬浮生长能力、B细胞表面标志物表达,以及在标准淋巴组织培养基中稳定增殖的能力。 作为非肿瘤来源的EBV永生化淋巴母细胞系,WIL2-S广泛应用于免疫学、遗传毒性及DNA修复研究的参考模型。

由于其稳定的核型及对DNA损伤剂的明确反应特性,WIL2-S细胞系在细胞遗传学和诱变试验中应用广泛,尤其适用于小核试验和染色体不稳定性检测。 该细胞系在DNA修复通路方面表现优异,常作为对照组用于评估氧化应激、辐射诱导损伤及化疗致突变性的研究。其淋巴样起源与可重复的增殖特性,使其适用于在受控实验条件下体外评估断裂致突变与非断裂致突变效应。

由于WIL2-S细胞系并非源自恶性肿瘤,而是EBV永生化的正常B细胞谱系,它为区分癌症特异性分子改变与普通淋巴细胞反应提供了重要基线模型。研究人员常将其作为非转化参照系,用于基因组稳定性、免疫细胞信号传导及细胞应激反应机制的研究。

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。
