01General information

Description

SK-MEL-29.1是一种黑色素瘤细胞系,它与免疫系统的相互作用,特别是细胞毒性T淋巴细胞(CTL)识别方面的相互作用已被广泛研究。这种 SK-MEL-29 黑色素瘤细胞系的亚克隆已被用于免疫学研究,以确定自体 CTL 识别的特定抗原。这些 CTL 可选择性地靶向表达特定抗原的黑色素瘤细胞,而放过非癌细胞。在免疫选择实验中发现,SK-MEL-29.1表达的稳定抗原对CTL特异性裂解黑色素瘤细胞非常重要,这为了解肿瘤的免疫原性和免疫逃避提供了线索。

涉及 SK-MEL-29.1 的一项重要研究证明了它在癌症免疫疗法研究中的用途。研究表明,从患者 AV 中提取的 CTL 克隆可有效靶向同时表达多种抗原的 SK-MEL-29.1 细胞。这使 SK-MEL-29.1 成为了解如何调整免疫反应以靶向黑色素瘤特定抗原的重要模型。这些 CTL 克隆识别和裂解黑色素瘤细胞的能力为免疫治疗策略的开发提供了宝贵的信息,包括产生个性化癌症疫苗的可能性。

此外,SK-MEL-29.1 细胞还在基于病毒的癌症疫苗开发中进行了测试。感染新城疫病毒(NDV)(一种具有溶瘤和免疫刺激特性的病毒)的结果表明,SK-MEL-29.1 即使在伽马射线照射后也能被 NDV 有效感染,使其成为开发癌症活疫苗的合适候选细胞。这种感染增强了肿瘤细胞的免疫原性,导致更强大的抗肿瘤免疫反应,进一步支持了 SK-MEL-29.1 在疫苗研究中的应用。

05Handling and culture

Culture medium
DMEM,w:4.5 克/升葡萄糖,w:4 毫摩尔 L-谷氨酰胺,w:3.7 克/升 NaHCO3,w:1.0 毫摩尔丙酮酸钠(Cytion 编号 820300a)。
Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS
Dissociation reagent
Accutase
Subculturing
去除粘附细胞上的旧培养基,用不含钙和镁的 PBS 冲洗。T25 烧瓶用 3-5 毫升 PBS,T75 烧瓶用 5-10 毫升。然后用 Accutase 完全覆盖细胞,T25 烧瓶用 1-2 毫升,T75 烧瓶用 2.5 毫升。让细胞在室温下孵育 8-10 分钟,使其分离。孵育后,用 10 毫升培养基轻轻混合细胞使其重悬,然后用 300xg 离心 3 分钟。弃去上清液,用新鲜培养基重悬细胞,并将其转移到已装有新鲜培养基的新烧瓶中。
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。
