01General information
- Description
OVCAR-8-Luc细胞是人类卵巢腺癌细胞系OVCAR-8的生物发光衍生物,该细胞系最初是从一名晚期成人患者体内建立的。这些细胞经过基因工程改造,可稳定表达荧光素酶——一种在底物存在下能催化发光反应的酶,从而能够对细胞活动进行高灵敏度、无创的监测。 亲本 OVCAR-8 细胞系具有生长侵袭性强、基因组不稳定以及高分化浆液性卵巢癌的典型特征,因此成为研究卵巢肿瘤生物学的广泛应用模型。
萤火虫蛋白的引入使 OVCAR-8-Luc 细胞能够应用于纵向体内成像,特别是在异种移植和原位肿瘤模型中,通过生物发光成像可随时间推移定量追踪肿瘤负荷和转移扩散情况。这些细胞保留了亲本细胞系的关键分子和表型特征,包括与卵巢癌进展相关的通路改变,例如 p53 功能障碍和细胞周期调控失调。 因此,OVCAR-8-Luc细胞非常适合用于评估治疗疗效、肿瘤生长动力学和转移行为,以及在前临床研究中研究肿瘤微环境相互作用。

- 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.

- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
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.
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.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
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.
Centrifuge the mixture at 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.
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。

09Legal and safety
- Safety precautions
- 计划将低温样品储存在液氮中以便将来解冻时,必须遵守严格的安全措施。在将冷冻样本移入或移出液氮罐时,必须穿戴适当的防护手套和防护服,并使用面罩或安全护目镜。这样做是为了降低在移出时因冷冻样品爆炸而造成伤害的风险,因为爆炸可能导致锋利的碎片飞溅。
