01General information

Description

HCT116-GFP 是人类结直肠癌细胞系 HCT116 的基因改造衍生物,经过工程改造后可持续表达绿色荧光蛋白(GFP)。 亲本 HCT116 细胞系源自一名成年患者的结肠癌,被广泛用作错配修复缺陷(MMR 缺陷)结直肠癌的模型。 细胞遗传学分析表明,HCT116 细胞通常表现出近二倍体的核型,具有明确的染色体改变,包括微卫星不稳定性阳性结直肠肿瘤特有的结构重排和拷贝数变异。 引入 GFP 报告基因后,可以在不显著改变亲本细胞系固有遗传和表型特性的情况下,实时观察细胞行为。

HCT116-GFP 细胞中的 GFP 标记通常通过稳定转染实现,从而产生均匀的荧光,便于活细胞成像、细胞追踪以及对增殖、迁移和肿瘤生长动态的定量分析。 这种改造在体外实验和体内异种移植模型中尤为宝贵,在这些模型中,GFP的表达允许对肿瘤进展、转移扩散以及对治疗干预的反应进行无创监测。 基于荧光的表型分析方法已证明,包括 HCT116 在内的结肠癌细胞系表现出独特的细胞内特征,这些特征可通过成像方法捕捉,这印证了 GFP 等荧光报告基因在高通量筛选应用中的实用性。

HCT116-GFP是研究结直肠癌生物学的一款可靠工具,可在基础和转化研究背景下,对肿瘤细胞行为、微环境相互作用以及治疗疗效进行详细分析。

基因修饰:通过复制缺陷型慢病毒转导进行稳定修饰,以表达 ZsGreen1 绿色荧光蛋白报告基因;在嘌呤霉素(1–5 µg/mL)筛选下维持为多克隆细胞群。S1/BSL-1 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。
