01General information
- Description
托莱多细胞系是一种弥漫性大B细胞淋巴瘤(DLBCL)细胞系,最初是从一名DLBCL患者的外周血中建立的,该患者在接受大剂量化疗和骨髓移植后,脑部出现了继发性淋巴瘤。 该细胞系表现出复杂的核型,存在多种染色体畸变,但不具备伯基特淋巴瘤特有的易位。
托莱多细胞系的一个独特特征是其不表达免疫球蛋白(Ig)多肽链,且缺乏可检测到的恒定(C)区基因片段。 尽管如此,托莱多细胞系仍保留了其可变(V)基因片段发生体细胞超突变的能力,这通常是生发中心 B 细胞中观察到的现象。 有趣的是,尽管托莱多细胞系缺乏显著的克隆突变,但其克隆内突变的积累频率却高于达乌迪(Daudi)和拉吉(Raji)等其他淋巴瘤细胞系。这表明突变过程可能在体外转化后仍在持续,这可能为研究体细胞超突变的分子机制提供了一个有价值的模型。

- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
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.
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.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
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.
Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.
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.
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。

- 成人
- Ethnicity
- 高加索人
09Legal and safety
- Safety precautions
- 计划将低温样品储存在液氮中以便将来解冻时,必须遵守严格的安全措施。在将冷冻样本移入或移出液氮罐时,必须穿戴适当的防护手套和防护服,并使用面罩或安全护目镜。这样做是为了降低在移出时因冷冻样品爆炸而造成伤害的风险,因为爆炸可能导致锋利的碎片飞溅。
