01General information

Description

MOLT-4 是一种 T 淋巴细胞系,来源于 1971 年一名急性淋巴细胞白血病(ALL)复发的 19 岁男性患者的外周血。它是 MOLT-3 的姊妹细胞系,而 MOLT-4 则显示出不寻常的 T 细胞抗原受体γ-链基因(T-γ)重排。MOLT-4 细胞的倍增时间约为 30 小时,悬浮生长,在未经处理的裸鼠、经抗淋巴细胞血清处理的小鼠和经 X 射线照射的小鼠体内均可致瘤。

MOLT-4 细胞的染色体数目为超四倍体,24% 的细胞染色体数目为 95,但染色体结构异常稳定且反复出现,端粒长度较长。MOLT-4 表达多种 T 细胞标记,包括 CD1、CD2、CD3A、CD3B、CD3C、CD4、CD5、CD6 和 CD7。它们还表达高水平的末端脱氧核苷酸转移酶(TdT)。

MOLT-4 细胞系不产生免疫球蛋白或 Epstein-Barr 病毒。细胞来源患者曾接受过多药化疗。p53 基因第 248 个密码子上有一个 G -> A 突变,P53 没有表达。该细胞系最初受到支原体污染,但后来已用抗生素治愈。

06Handling 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% FBS
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
1 × 10⁵ 个细胞/平方厘米
Fluid renewal
每周 2 至 3 次
Post-thaw recovery
24 至 48 小时
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。
