01General information

Description

U-87 MG-RFP细胞是人类胶质母细胞瘤星形细胞瘤细胞系U-87 MG的一种荧光标记变体,该细胞系最初源自一名成年患者的恶性胶质瘤。 母系 U-87 MG 细胞系因其生长特性表征明确、具有成瘤潜力且与高级别星形细胞瘤相关,被广泛用作胶质母细胞瘤的体外模型。 这些细胞表现出黏附性生长,具有上皮样形态,通常用于研究细胞增殖、侵袭、血管生成以及对缺氧条件的反应等过程。

在 U-87 MG-RFP 细胞中,红色荧光蛋白(RFP)的稳定表达使得在体外和体内系统中均可实时观察肿瘤细胞的行为。这种改造促进了活细胞成像、原位异种移植模型中的肿瘤追踪以及脑组织内侵袭性生长模式分析等应用。 U-87 MG-RFP细胞对于研究胶质母细胞瘤的进展、肿瘤与微环境的相互作用,以及利用荧光成像方法评估治疗策略具有特别重要的价值。

基因修饰:通过复制缺陷型慢病毒转导进行稳定修饰,以表达红色荧光蛋白(RFP)报告基因;在嘌呤霉素筛选(1–5 µg/mL)条件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 red fluorescent protein (RFP) 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。
