01General information

Description

Neuro-2a-Luc 是 Neuro-2a(N2a)小鼠神经母细胞瘤细胞系的荧光素酶表达衍生物。Neuro-2a 细胞源自小鼠神经嵴来源的神经母细胞瘤组织,被广泛用作神经元分化、神经毒性研究、信号转导研究以及神经肿瘤学研究的体外模型。 荧光素酶报告基因的稳定表达使得对存活细胞和细胞活性进行灵敏、定量的生物发光检测成为可能,这使得 Neuro-2a-Luc 特别适用于体外和体内实验系统的纵向监测。根据报告基因的设计,荧光素酶的表达可以是恒定的,也可以与特定信号通路的启动子活性相关联。

Neuro-2a-Luc细胞常用于肿瘤生长追踪、高通量药物筛选、神经分化检测以及治疗反应的实时评估。在异种移植和转移模型中,基于荧光素酶的生物发光成像技术能够以高灵敏度对肿瘤负荷和疾病进展进行无创监测。 源自Neuro-2a的系统还被广泛用于研究神经元形态、神经突生长、凋亡、氧化应激以及与神经退行性疾病相关的机制。荧光素酶修饰有助于快速定量分析细胞增殖、细胞毒性、转录活性,或针对药理学或遗传学扰动的信号通路调节。

与其他工程化报告基因细胞系一样,Neuro-2a-Luc的实验表现可能取决于多种因素,包括荧光素酶构建体的整合位点、启动子配置、底物兼容性,以及连续传代过程中报告基因表达的稳定性。对于高度专业化的实验应用,可能需要额外的表征数据,包括有关荧光素酶变体、筛选标记和验证实验的详细信息。

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.

Incubation atmosphere

37°C, 5%CO2, 加湿环境。

Supplements
在培养基中添加 10% FBS 和 1% NEAA
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 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。
