01General information

Description

SW620-GFP 細胞是人類結直腸腺癌細胞系 SW620 的螢光標記變體,該細胞系最初源自一名成人患者淋巴結中的轉移病灶。 這些細胞經過基因工程改造,可穩定表達綠色螢光蛋白(GFP),從而能夠利用螢光成像技術,即時直接觀察細胞形態、增殖及遷移行為。 親本 SW620 細胞系的特徵在於其源自轉移病灶,並展現出與晚期大腸直腸癌相關的特徵,包括增強的運動性、侵襲能力以及改變的細胞黏附特性。

SW620-GFP 細胞中 GFP 的表達,有助於進行活細胞追蹤、侵襲性檢測,以及在異種移植模型中的體內成像等應用,藉此可非侵入性地監測腫瘤的生長與擴散。 這些細胞保留了親本細胞系的主要分子特徵,包括通常與結直腸癌進展相關的突變,以及 Wnt/β-catenin 和 MAPK 等訊號傳導路徑的失調。 因此,SW620-GFP 細胞是研究轉移機制、腫瘤微環境相互作用,以及評估針對晚期大腸直腸癌之抗癌療法的寶貴工具。

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.

06Handling and culture

Culture medium
DMEM
Incubation atmosphere

37°C,5% CO₂,加濕環境。

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。
