01General information

Description

HCC827-Luc 是人类 HCC827 肺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 HCC827 细胞系源自肺腺癌,其显著特征是携带激活型 EGFR 第 19 外显子缺失(del E746-A750),这使其对吉非替尼、 厄洛替尼和奥西替尼等EGFR酪氨酸激酶抑制剂(TKIs)表现出高度敏感性。因此,HCC827是研究EGFR驱动型肺癌生物学、获得性TKI耐药机制以及新一代靶向治疗疗效的最广泛使用的临床前模型之一。

HCC827-Luc中稳定的荧光素酶整合,使得在免疫缺陷宿主中的异种移植和原位肺肿瘤模型中,能够对肿瘤负荷进行灵敏、定量的生物发光成像(BLI)。 发出的生物发光信号与存活肿瘤细胞数量呈正相关,支持对肿瘤植入、生长动力学、转移扩散及治疗反应进行无创的纵向监测。 这使得 HCC827-Luc 特别适合在临床前体内环境中评估 EGFR 靶向药物、联合疗法以及逆转耐药策略的疗效。

HCC827-Luc 保留了亲本 HCC827 细胞系的关键分子和表型特征,包括 EGFR 第 19 外显子缺失状态以及对已获批 EGFR 抑制剂的敏感性。 荧光素酶修饰显著提高了实验灵敏度和通量,可进行实时药效学评估,并有助于高通量药物筛选和EGFR通路生物学机制的研究。研究人员在将其用于定量成像或药理学研究之前,应在其特定的实验条件下验证荧光素酶活性、EGFR突变状态和生长动力学。

GMO-S1
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
在培养基中添加 10% FBS
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。
