01General information

Description

A549-Luc 是人类肺腺癌细胞系 A549 的基因工程衍生物,经过改造可稳定表达荧光素酶报告基因。亲本 A549 细胞系源自一名成年患者的肺癌,被广泛用作非小细胞肺癌(NSCLC)的模型,尤其是腺癌。 A549细胞呈现上皮细胞形态,并具有与肺癌生物学相关的关键分子特征,包括KRAS基因突变以及调控增殖、代谢和氧化应激反应的信号通路改变。这种表达荧光素酶的变体在保留这些固有特性的同时,还具备生物发光检测功能。

通过整合荧光素酶基因,在添加荧光素底物后,可通过生物发光成像对存活细胞进行灵敏、无创的定量检测。这使得在体外实验和体内异种移植模型中,均可实时监测细胞增殖、肿瘤生长及治疗反应。 发出的光信号与代谢活跃细胞的数量相关,这使得 A549-Luc 特别适用于肿瘤动力学、转移及药物疗效的纵向研究。稳定的整合确保了报告基因的持续表达,尽管信号强度可能因克隆选择和实验条件而有所不同。

A549-Luc 保留了亲本 A549 细胞系的生物学特性,包括其在肺癌进展、炎症以及对化疗或靶向药物反应研究中的应用价值。 荧光素酶报告基因的引入显著增强了实验灵活性,支持高通量药物筛选、体内成像以及随时间推移的肿瘤负荷定量评估。因此,A549-Luc是肺癌转化研究及新型治疗策略临床前评估的宝贵工具。

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.

05Handling and culture

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

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

06Quality 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。
