01General information
- Description
SW620-GFP细胞是人类结直肠腺癌细胞系SW620的一种荧光标记变体,该细胞系最初源自一名成年患者淋巴结中的转移病灶。 这些细胞经过基因工程改造,可稳定表达绿色荧光蛋白(GFP),从而能够利用基于荧光的成像技术,实时直接观察细胞形态、增殖和迁移行为。 亲本 SW620 细胞系以其转移性来源为特征,并表现出与晚期结直肠癌相关的特征,包括增强的运动性、侵袭能力和改变的细胞粘附特性。
SW620-GFP 细胞中 GFP 的表达促进了活细胞追踪、侵袭实验以及异种移植模型中的体内成像等应用,通过这些应用可以无创地监测肿瘤的生长和扩散。 这些细胞保留了亲本细胞系的关键分子特征,包括通常与结直肠癌进展相关的突变,以及 Wnt/β-catenin 和 MAPK 等信号通路的失调。 因此,SW620-GFP细胞是研究转移机制、肿瘤微环境相互作用以及评估针对晚期结直肠癌的抗癌疗法的宝贵工具。
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;在嘌呤霉素筛选(1–5 µg/mL)条件下作为多克隆细胞群维持。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.

06Handling and culture
- Culture medium
- DMEM
- Incubation atmosphere
37°C, 5%CO2, 加湿环境。
- 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。
