01General information

Description

U-87 MG-RFP 細胞是人類膠質母細胞瘤星形細胞瘤細胞系 U-87 MG 的螢光標記變體,該細胞系最初源自一名成人患者的惡性膠質瘤。 由於其生長特性已充分闡明、具有成瘤潛力,且與高階星形細胞瘤密切相關,母系 U-87 MG 細胞系被廣泛用作膠質母細胞瘤的體外模型。 這些細胞呈現黏附性生長,具有上皮樣形態,常被用於研究細胞增殖、侵襲、血管生成以及對缺氧條件的反應等過程。

在 U-87 MG-RFP 細胞中,紅色螢光蛋白(RFP)的穩定表達,使得無論在體外或體內系統中,皆能即時觀察腫瘤細胞的行為。此種改造有助於進行活細胞成像、在原位異種移植模型中追蹤腫瘤,以及分析腦組織內的侵襲性生長模式等應用。 U-87 MG-RFP 細胞對於研究膠質母細胞瘤的進展、腫瘤與微環境的相互作用,以及利用螢光成像技術評估治療策略,具有特別重要的價值。

基因改造:透過複製無能的慢病毒轉導進行穩定改造,以表達紅色螢光蛋白(RFP)報告基因;在嘌呤酶(1–5 µg/mL)篩選下維持為多克隆細胞群。S1/BSL-1 防護等級。

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
作為冷凍保存培養基,我們使用完全生長培養基加上 10% 的二甲基亞砜(DMSO),以確保解凍後的細胞存活率達到適當水準。
Storage conditions

若需長期保存,請將試管置於溫度約為 −150 至 −196 °C 的氣相液氮中。僅在轉移至液氮之前,可將試管暫時存放於 −80 °C 環境中,作為短期過渡步驟。

Shipping conditions

冷凍保存的細胞系會以乾冰冷藏,並裝於經驗證的隔熱包裝中,包裝內含有足夠的冷媒,以確保在運輸過程中溫度維持在約 −78 °C。收到貨物後,請立即檢查容器,並盡快將試管轉移至適當的儲存場所。
