01General information

Description

A2780-GFP 是人类卵巢癌细胞系 A2780 的基因改造衍生物,经过工程改造可稳定表达绿色荧光蛋白(GFP)。 亲本 A2780 细胞系源自一名成年患者的卵巢肿瘤,被广泛用作上皮性卵巢癌的模型,特别是在化疗反应研究中。该细胞系以其对顺铂等铂类药物相对敏感而著称,因此成为研究药物作用机制和耐药机制的宝贵模型。 这种表达GFP的变体在保留上述生物学特性的同时,还整合了荧光报告基因,从而提高了其实验应用价值。

GFP的稳定表达使得研究人员能够在各种实验条件下对A2780-GFP细胞进行实时可视化和定量分析。基于荧光的检测方法使研究人员能够监测细胞在体外的增殖、形态、迁移和存活情况,并追踪体内肿瘤的生长和扩散。 这在异种移植和转移模型中尤为有利,因为 GFP 有助于将肿瘤细胞与周围宿主组织区分开来。尽管表达水平可能因转导方法和克隆选择而有所不同,但荧光信号在各传代过程中通常保持稳定。

A2780-GFP保留了亲本A2780细胞系的核心分子和表型特征,包括与DNA损伤应答、凋亡及化疗敏感性相关的信号通路。 因此,该模型常用于高内涵成像检测、药物筛选平台以及需要对肿瘤细胞行为进行时空分辨的共培养系统。GFP的引入显著增强了该模型的多功能性,支持其在卵巢癌研究、治疗评估以及肿瘤细胞动力学研究中的应用。

基因改造:通过复制缺陷型慢病毒转导进行稳定改造,以表达ZsGreen1绿色荧光蛋白报告基因;在嘌呤霉素筛选(1–5 µg/mL)条件下作为多克隆群体维持。S1/BSL-1级生物安全等级。

GMO status details
GMO-S1: This cell line contains a stably integrated ZsGreen1 green fluorescent protein reporter 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
  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。
