01General information

Description

BJAB 细胞系是 1973 年从一个被诊断患有 Epstein-Barr 病毒(EBV)阴性伯基特淋巴瘤的 5 岁非洲女孩身上建立的。这一特殊来源对研究至关重要,因为它为研究不受 EBV 影响的伯基特淋巴瘤提供了一个独特的模型。BJAB 细胞的 EBV 阴性状态使研究人员能够在不受病毒干扰的情况下研究导致淋巴瘤发生的遗传和环境因素。

BJAB 细胞常用于肿瘤研究,特别是用于探索伯基特淋巴瘤的病理生理学,以及测试针对该病的治疗策略。该细胞系显示出伯基特淋巴瘤的许多标志性特征,包括高增殖率和特征性免疫表型。它的遗传稳定性和培养的稳健性使其成为体外实验的重要工具,用于了解淋巴瘤生物学特性和评估抗癌药物的疗效。

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 20% FBS、10 mM HEPES
Subculturing
通过定期添加或更换培养基来维持细胞培养。初始培养时细胞密度应为5×10⁵个细胞/毫升,并保持细胞浓度在3×10⁵至1×10⁶个细胞/毫升范围内以获得最佳生长效果。
Seeding density
3 × 10⁵ 个细胞/毫升
Fluid renewal
每 3 至 5 天
Post-thaw recovery
让细胞从冷冻过程中恢复至少 48 小时。
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。
