01General information

Description

B16-F10-Luc是B16-F10小鼠黑色素瘤细胞系的生物发光衍生物,该细胞系最初是从C57BL/6小鼠体内自发发生的黑色素瘤中建立的。由于其具有较高的转移潜能,且在同基因C57BL/6宿主中能实现强效且可重复的植入,亲本B16-F10细胞系在癌症研究中被广泛应用。 在 B16-F10-Luc 细胞中,通过慢病毒转导,将荧光素酶基因稳定整合在恒定活性启动子(通常为 EF-1α 或 CMV)的控制下,从而在多次传代过程中实现高水平、稳定的荧光素酶表达。

在存在荧光素底物的情况下,B16-F10-Luc 细胞会发出生物发光信号,从而能够对活体动物的肿瘤生长、扩散和转移进行非侵入性的定量体内生物发光成像 (BLI)。 该细胞系适用于 C57BL/6 小鼠的皮下和静脉注射(实验性转移)模型,转移性克隆优先在肺部形成。发光强度与存活细胞数呈线性正比,从而可在无需在每个时间点处死动物的情况下,对肿瘤负荷进行实时、纵向监测。荧光素酶的表达不会显著改变 B16-F10 细胞的体外或体内生长动力学。

主要应用包括在同系小鼠模型中评估抗肿瘤药物、免疫疗法及抗转移化合物,以及在肿瘤学临床前研究中进行定量药效学成像。

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

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。
