01General information

Description

B16-F10-Luc 是 B16-F10 小鼠黑色素瘤細胞系的生物發光衍生物,該細胞系最初是從一隻 C57BL/6 小鼠身上自然發生的黑色素瘤建立而來。 其親本 B16-F10 細胞系因其高度的轉移潛能,以及在同基因 C57BL/6 宿主中強健且可重複的植入能力,而被廣泛應用於癌症研究。 在 B16-F10-Luc 細胞中,透過慢病毒轉導,將螢火蟲基因穩定整合至由構成性活化啟動子(通常為 EF-1α 或 CMV)所控制的區域,從而實現跨傳代的高水準、穩定螢火蟲基因表達。

在存在螢光素底物的情況下,B16-F10-Luc 細胞會發出生物發光訊號,從而能夠對活體動物的腫瘤生長、擴散和轉移進行非侵入性、定量的體內生物發光成像(BLI)。 該細胞系適用於 C57BL/6 小鼠的皮下及靜脈注射(實驗性轉移)模型,且轉移性菌落傾向於在肺部形成。 發光強度與存活細胞數呈線性正比,因此無需在每個時間點犧牲動物,即可對腫瘤負荷進行即時、縱向監測。螢光素酶的表達不會顯著改變 B16-F10 細胞在體外或體內的生長動力學。

主要應用包括在同基因型模型中評估抗腫瘤藥物、免疫療法及抑制轉移的化合物,以及在腫瘤學前臨床研究中進行定量藥效學成像。

GMO status
GMO-S1
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.

06Handling and culture

Culture medium
DMEM,含 4.5 g/L 葡萄糖、4 mM L-谷氨醯胺、3.7 g/L NaHCO₃ 及 1.0 mM 丙酮酸鈉(Cytion 產品編號 820300a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Dissociation reagent
Accutase
Subculturing
從貼壁細胞中移除舊培養基,並用不含鈣和鎂的PBS洗滌細胞。T25培養瓶使用3-5毫升PBS,T75培養瓶則使用5-10毫升。 接著,用 Accutase 完全覆蓋細胞,T25 培養瓶使用 1–2 毫升,T75 培養瓶則使用 2.5 毫升。將細胞於室溫下孵育 8–10 分鐘,使其脫附。 孵育後,將細胞與 10 毫升培養基輕柔混合以使其重新懸浮,然後以 300xg 離心 3 分鐘。棄去上清液,將細胞重新懸浮於新鮮培養基中,並轉移至已預先加入新鮮培養基的新培養瓶中。

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。
