01General information

Description

A2780-GFP 是人類卵巢癌細胞系 A2780 的基因改造衍生物,經工程改造後可穩定表達綠色螢光蛋白(GFP)。 原始的 A2780 細胞系是從一名成年患者的卵巢腫瘤中建立的,廣泛用作上皮性卵巢癌的模型,特別是在研究化療反應方面。該細胞系以其對順鉑等鉑類藥物具有相對敏感性而聞名,使其成為研究藥物作用機制與抗藥性機制的寶貴系統。 這種表達 GFP 的變異株在保留上述生物特性的同時,還整合了螢光報告基因,從而增強了其實驗應用價值。

GFP 的穩定表達使研究人員能在各種實驗情境下,對 A2780-GFP 細胞進行即時可視化觀察與定量分析。基於螢光的檢測技術,不僅能讓研究人員在體外監測細胞增殖、形態、遷移及存活率,還能追蹤體內腫瘤的生長與轉移。 這在異種移植和轉移模型中尤為有利,因為 GFP 有助於將腫瘤細胞與周圍宿主組織區分開來。儘管表達水平可能因轉導方法和克隆選擇而異,但螢光訊號在各傳代過程中通常保持穩定。

A2780-GFP 保留了親本 A2780 細胞系的核心分子與表型特徵,包括與 DNA 損傷反應、凋亡及化療敏感性相關的信號傳導途徑。 因此,該細胞系常被應用於高內容成像檢測、藥物篩選平台以及需要對腫瘤細胞行為進行時空解析的共培養系統中。GFP 的加入顯著增強了此模型的多功能性,支援其在卵巢癌研究、治療評估以及腫瘤細胞動態研究中的應用。

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 ZsGreen1 綠色螢光蛋白報告基因;在嘌呤酶篩選(1–5 µg/mL)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 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。
