01General information
- Description
CCRF-CEM 细胞是一种人类 T 淋巴细胞,常用于免疫肿瘤学和免疫学研究。这些细胞是从一名患有急性淋巴细胞白血病(ALL)的 4 岁女性白种人的外周血中分离出来的。
CCRF-CEM 悬浮生长,在旋转瓶中培养时细胞密度很高。CCRF-CEM 细胞的核型分析表明,其染色体数目一般为 47 条,从 41 到 95 不等。它们没有显示特定染色体的持续丢失或增殖,也没有标记染色体。不过,在 45 条染色体的细胞中,28% 的细胞显示为 C-,53% 的细胞多了一条 D,35% 的细胞多了一条 F。
CCRF-CEM 细胞具有致瘤性,可导致叙利亚仓鼠肿瘤。这些细胞表达 CD3、CD5、CD7 和 CD4 基因和抗原。此外,同工酶分析显示 ADA,1;ES-D,1;G6PD,B;GLO-I,1;PEP-D,1;PGD,C;PGM1,1;PGM3,0。
一项研究表明,白藜芦醇和泼尼松龙的组合能以时间和剂量依赖的方式诱导 CCRF-CEM 细胞凋亡。联合治疗对 BAx 的过表达和 BCL2 的下调具有协同作用。

- 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
- 以1×10⁵个细胞/毫升的浓度启动新培养。
- Fluid renewal
- 每 3 天
- Post-thaw recovery
- 让细胞从冷冻过程中恢复至少 48 小时。
- 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。

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。
