01General information

Description

HeLa-Luc 細胞是人類 HeLa 子宮頸腺癌細胞系的生物發光衍生細胞系,經基因工程改造後可持續表達螢火蟲蛋白酶報告基因。在添加螢火蟲素底物後,這些細胞會發出可量化的發光訊號,該訊號與存活細胞數及代謝活性呈直接相關。 此特性使得無論在體外實驗或體內成像應用中,皆能對腫瘤細胞的增殖、存活及擴散進行高靈敏度且非侵入性的監測。HeLa-Luc 細胞不僅保留了親代 HeLa 細胞強勁的生長特性與上皮細胞形態,同時還為縱向實驗分析提供了額外的光學讀數。

由於具有表達螢光素酶的表型,HeLa-Luc 細胞特別適用於免疫缺陷動物模型中的異種移植與轉移研究,在此類研究中,可利用即時生物螢光成像技術,隨時間推移追蹤腫瘤負荷及治療反應。 在細胞基檢測中,這些細胞廣泛應用於高通量藥物篩選、細胞毒性測試、基因遞送系統評估,以及癌細胞訊號傳導與凋亡的研究。穩定的報告基因表達亦支援在共培養系統及需要動態監測細胞存活率或轉錄活性的實驗模型中進行可重複的定量分析。

與親代 HeLa 細胞一樣,HeLa-Luc 細胞展現出與人類乳突病毒 18 型(HPV-18)相關的轉化型子宮頸癌細胞所特有的基因組不穩定性及高增殖能力。 實驗條件、螢光素酶載體設計、啟動子選擇及篩選策略可能因實驗室或商業來源而異,這可能影響報告基因的強度與長期表達穩定性。因此,研究人員應在進行大規模實驗應用前,先根據其特定的培養與檢測條件,驗證螢光素酶活性、生長動力學及表型一致性。

GMO status details
GMO-S1: This cell line contains a stably integrated firefly luciferase reporter cassette (Luc2, codon-optimized) 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。
