01General information

Description

SU-DHL-1是一种人类无性大细胞淋巴瘤(ALCL)细胞系,是从一名被诊断为弥漫组织细胞淋巴瘤的儿童胸腔积液中建立的。它是最早建立的连续培养人淋巴瘤细胞系之一,在表型和基因方面都有严格的特征。从形态上看,SU-DHL-1 保留了原发肿瘤的特征,包括含脂的大细胞质空泡。组织化学研究显示,非特异性酯酶和酸性磷酸酶具有活性。与淋巴母细胞系不同,SU-DHL-1 的爱泼斯坦-巴氏病毒核抗原(EBNA)呈阴性,不表达表面免疫球蛋白,这进一步将其与 B 淋巴细胞衍生系区分开来。

由于染色体易位 t(2;5)(p23;q35),导致 NPM1-ALK 融合蛋白的表达,SU-DHL-1 成为 ALK 阳性 ALCLL 的标志性模型。这种融合蛋白具有组成型酪氨酸激酶活性,在 ALK+ ALCL 的致癌过程中起着核心作用。该细胞系是LL-100面板的一部分,LL-100面板是一套用于高通量分子剖析的白血病和淋巴瘤模型。SU-DHL-1已被广泛用于ALCL内的致癌信号转导、靶向治疗开发和转录调控等相关研究,使其成为了解和治疗这种侵袭性T细胞淋巴瘤亚型的关键工具。

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。
