01General information

Description

A20 细胞系来源于小鼠的网状细胞肉瘤,被广泛用于免疫学和癌症研究。网状细胞肉瘤是一种 B 细胞淋巴瘤,A20 细胞是研究 B 细胞淋巴瘤生物学和免疫反应的宝贵模型。这些细胞对研究 B 细胞的发育、活化、信号传导以及肿瘤细胞与免疫系统之间的相互作用机制特别有用。此外,A20 细胞在研究细胞因子的产生和功能方面起着至关重要的作用,而细胞因子对免疫调节至关重要。

A20 细胞具有淋巴细胞形态,表达典型的 B 细胞表面标志物,包括表面免疫球蛋白和主要组织相容性复合体 (MHC) 分子。研究人员利用 A20 细胞研究抗原呈递、B 细胞受体信号转导以及各种细胞因子在免疫反应中的作用。这些细胞还有助于开发和测试免疫疗法,如单克隆抗体和检查点抑制剂,以治疗B细胞淋巴瘤和其他血液恶性肿瘤。此外,A20 细胞还是临床前研究中评估新型治疗药物疗效和安全性的模型。A20 细胞在免疫学研究和了解 B 细胞病理生理学方面的实用性凸显了其在推动癌症研究和开发新治疗策略方面的重要性。

05Handling 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
在培养基中加入 10%热灭活 FBS,再加入 2.5 g/L 葡萄糖和 10 mM HEPES。
Subculturing
悬浮细胞:用新鲜培养基移取基质中的细胞。要获得单细胞,可将悬浮液通过 22 号针头数次,然后分装到新的烧瓶中。
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.

06Quality 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。
