01General information

Description

K-562-GFP 細胞是人類慢性骨髓性白血病(CML)細胞系 K-562 的基因改造變體,最初源自一名處於爆發期(blast crisis)的成人患者的外周血。 親代 K-562 細胞系的特徵在於具有費城染色體,這會產生具有構成性酪胺酸激酶活性的 BCR-ABL 融合蛋白,從而驅動細胞不受控制地增殖與存活。 K-562 細胞具有紅白血病特徵,並可在特定實驗條件下被誘導沿紅系、巨核細胞系或單核細胞系進行分化,使其成為研究造血分化與白血病生物學的多功能模型。

將綠色螢光蛋白(GFP)導入 K-562 細胞,可實現體外與體內白血病細胞行為的即時可視化與追蹤。 K-562-GFP 細胞廣泛應用於涉及細胞增殖、遷移及藥物反應的檢測,以及用於共培養系統以研究其與基質細胞或免疫細胞的相互作用。螢光標記便於進行流式細胞術、活細胞成像及高通量篩選等應用。

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;在嘌呤黴素(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 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.

Fluid renewal
每週 2 至 3 次
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。
