01General information

Description

SK-BR-3-Luc 是人类 SK-BR-3 乳腺腺癌细胞系的生物发光衍生物,经基因工程改造后可稳定表达萤火虫荧光素酶报告基因。 亲本 SK-BR-3 细胞系源自一名 43 岁白人女性患者的乳腺腺癌胸腔积液转移灶,其特征为 HER2(ERBB2)基因扩增和过表达,因此被归类为 HER2 阳性乳腺癌模型。 SK-BR-3细胞呈现上皮样单层生长,被广泛用于研究HER2驱动的乳腺癌生物学,以及评估包括曲妥珠单抗、拉帕替尼、帕妥珠单抗以及曲妥珠单抗-德鲁克替康等抗体药物偶联物在内的HER2靶向疗法。

SK-BR-3-Luc 中稳定的荧光素酶整合使人们能够对免疫缺陷宿主中的异种移植模型进行敏感、定量的生物发光成像(BLI),以评估肿瘤负荷。 发出的发光信号与存活肿瘤细胞数量呈正相关,支持对肿瘤植入、生长动力学和治疗反应进行无创的纵向监测。 SK-BR-3-Luc 在针对乳腺癌 HER2 信号轴的抗 HER2 药物、抗体药物偶联物(ADC)、双特异性抗体及联合治疗策略的临床前评估中具有特别重要的价值,同时适用于高通量药物筛选和体内药效学研究。

SK-BR-3-Luc 保留了亲本 SK-BR-3 细胞系已确立的 HER2 扩增分子表型和生长特征。荧光素酶报告基因显著提高了体内成像研究的实验通量和灵敏度。 研究人员在进行大规模临床前应用前,应根据具体实验条件确认荧光素酶活性、HER2扩增状态及增殖动力学。

GMO status
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.

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。
