01General information

Description

NCI-N87-Luc 是人类 NCI-N87 胃腺癌细胞系的生物发光衍生物,经过基因工程改造,可稳定表达萤火虫荧光素酶报告基因。 亲本 NCI-N87 细胞系源自一名非洲裔男性患者的胃管状腺癌肝转移灶,其特征为 HER2(ERBB2)基因扩增和蛋白质过表达,因此成为 HER2 阳性胃癌的主要临床前模型之一。 NCI-N87细胞呈现上皮细胞形态,被广泛用于评估HER2靶向治疗(包括曲妥珠单抗、帕妥珠单抗和曲妥珠单抗-艾坦辛(T-DM1))的疗效。

NCI-N87-Luc 中稳定的荧光素酶整合,使得在免疫缺陷宿主的皮下和原位异种移植模型中,能够对肿瘤负荷进行灵敏、无创的生物发光成像 (BLI)。 发光信号与存活肿瘤细胞数量相关,有助于对肿瘤植入、生长动力学以及对 HER2 靶向药物或化疗药物的反应进行纵向监测。 NCI-N87-Luc 对于胃癌中抗体药物偶联物 (ADCs)、双特异性抗体以及新型 HER2 靶向策略的临床前评估,以及高通量药物筛选应用具有特别重要的价值。

NCI-N87-Luc 保留了亲本 NCI-N87 细胞系的 HER2 扩增分子表型和贴壁生长特征。荧光素酶报告基因提高了体内成像研究的实验通量和灵敏度。 研究人员在将其用于定量成像或药理学研究之前,应根据具体实验条件确认荧光素酶活性、HER2表达状态及增殖动力学。

GMO status details
GMO-S1: This cell line contains a stably integrated firefly luciferase reporter cassette (Luc2, codon-optimized) introduced via replication-incompetent lentiviral transduction. The resulting polyclonal cell population was maintained under puromycin selection (1–5 µg/mL). S1 containment is required. This classification applies only within Germany and may differ elsewhere.

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
在培养基中加入10% FBS、10 mM HEPES、2.5 g/L 葡萄糖和1 mM 丙酮酸钠
Dissociation reagent
Accutase,37°C下反应10分钟
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 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.

  7. Follow the procedure described under Post-Thaw Recovery

07Quality control and cryopreservation

Freeze medium
作为冷冻保存培养基,我们使用完全生长培养基+10% DMSO,以获得足够的解冻后存活率。
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。
