01General information

Description

T2 细胞系是 T1 人类淋巴母细胞系的衍生物,具有与抗原处理和呈递相关的独特特性。这些细胞缺乏与抗原加工相关的转运体(TAP),因此无法有效地将多肽转运到内质网,以装载到主要组织相容性复合体(MHC)I类分子上。这种缺陷使 T2 细胞在免疫学研究中,尤其是在与抗原呈递和 MHC I 类分子功能相关的研究中显得尤为重要。通过使用 T2 细胞,研究人员可以更好地了解免疫识别机制和 TAP 在抗原呈递中的作用。 T2 细胞还因其在细胞毒性 T 淋巴细胞(CTL)检测中的应用而闻名。由于缺乏 TAP,这些细胞表达的表面 MHC I 类分子水平很低,除非添加外源肽。利用这一特性可以精确研究肽与 MHC 的相互作用,并评估 CTL 对特定抗原的反应。此外,T2 细胞还可用于疫苗开发研究,特别是用于设计可增强免疫系统对抗原的呈递的策略。T2 细胞的独特特性使其成为基础和应用免疫学研究的重要工具。

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
在培养基中添加 10% 热灭活 FBS
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。
