01General information

Description

CA46 细胞系是一种从伯基特淋巴瘤中提取的人类细胞系,伯基特淋巴瘤是非霍奇金淋巴瘤的一种。该细胞系具有典型的转化 B 淋巴细胞系的特征,最初是从一名 39 岁男性的恶性细胞中提取的。CA46 细胞在肿瘤学研究中值得关注,特别是在了解 Epstein-Barr 病毒(EBV)阴性伯基特淋巴瘤的发病机制以及 B 细胞分化和转化的分子生物学基础方面。

在科学上,CA46 细胞在研究与 B 细胞发育和恶性肿瘤有关的基因表达方面发挥了重要作用。它们是 EBV 阴性的,这使研究人员能够在不受 EBV(许多淋巴恶性肿瘤中常见的混杂因素)影响的情况下研究肿瘤的特征和行为。该细胞系还是研究治疗药物疗效和淋巴瘤耐药机制的有用工具,有助于血液癌症靶向疗法的开发。

在研究环境中,CA46 细胞被用于评估对化疗药物的细胞毒性反应,以及探索参与 B 细胞增殖和凋亡的信号转导途径。CA46 细胞的基因组稳定性和对遗传操作的易感性使其能够进一步用于与癌症研究和治疗开发相关的分子生物学和遗传学研究。

06Handling and culture

Culture medium
RPMI 1640,w:2.0 mM 稳定谷氨酰胺,w:2.0 g/L NaHCO3(Cytion 文章编号 820700a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 20% 热灭活 FBS
Subculturing
通过上下吸取操作轻柔匀化烧瓶中的细胞悬液,随后取代表性样本测定每毫升细胞密度。用新鲜培养基将悬液稀释至1×10⁵细胞/毫升浓度,并将调整后的悬液分装至新烧瓶中进行后续培养。
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。
