01General information

Description

OCI-Ly19是一种人类B细胞淋巴瘤细胞系,来源于弥漫大B细胞淋巴瘤(DLBCL)患者的恶性淋巴结,DLBCL是一种常见的侵袭性非霍奇金淋巴瘤亚型。这种细胞系是研究弥漫性大 B 细胞淋巴瘤发病机制的重要工具,包括 B 细胞受体(BCR)信号传导异常、转录因子失调和驱动肿瘤进展的基因改变。OCI-Ly19经常被用于旨在了解DLBCL生物学和开发靶向治疗策略的研究中。

OCI-Ly19 细胞具有典型的 B 细胞形态,在标准培养条件下悬浮生长。该细胞系的染色体异常和基因改变是 DLBCL 常见的特征,包括影响 MYC 致癌基因和 BCL-2 家族成员的基因改变。这些特点使 OCI-Ly19 成为研究致癌信号通路(如 PI3K/AKT/mTOR 和 NF-κB 通路)的重要模型,这些通路对淋巴瘤中 B 细胞的存活和增殖至关重要。此外,OCI-Ly19 细胞表达成熟 B 细胞特有的表面标记,因此适合用于探索淋巴瘤中的抗原受体信号转导和免疫逃避机制。

OCI-Ly19 广泛用于临床前研究,以评估化疗药物、单克隆抗体(如抗 CD20 疗法)和针对关键信号通路的小分子抑制剂的疗效。该细胞系还被用于耐药性研究,特别是在了解DLBCL复发机制和确定克服耐药性的策略方面。OCI-Ly19具有良好的基因组特征和与DLBCL生物学的相关性,是淋巴瘤研究和治疗开发不可或缺的资源。

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。
