01General information

Description

EB1 细胞系是从伯基特淋巴瘤活检片段和细胞团块中提取的人源细胞系。该细胞系最初是在添加了 10%人血清的鹰氏基础培养基中培养的。独特的生长条件使细胞主要以自由浮动的单个或双个形式生长。EB1 细胞的倍增时间约为 48 小时,突出了其快速增殖的特点,而这正是淋巴母细胞的标志性特征。

从形态上看,EB1 细胞显示出统一的改变的淋巴母细胞特征,表明它们来源于淋巴组织。该细胞系已被广泛用于研究伯基特淋巴瘤,为研究淋巴恶性肿瘤的病理学提供了新的视角。它是研究各种实验条件下淋巴细胞生物学行为的宝贵模型,有助于探索治疗靶点和了解淋巴瘤的发展过程。

B 淋巴细胞
Karyotype
染色体频率分布 30 个细胞:2n = 46。该细胞系为非整倍体人类女性,染色体数目接近二倍体范围。正常染色体 N8、N11 和 N14 为单体,其余常染色体通常为配对。x 染色体通常为三体。有四条标记染色体。其中两条(标记染色体 M1 和 M3)涉及 N8 和 N14 染色体之间的互易位点,与大多数伯基特淋巴瘤细胞系有关。

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。
