01General information

Description

L6565 細胞源自 L6565 白血病小鼠脾細胞的胰臟懸浮液。 其染色體數目介於 38 至 144 之間。電子顯微鏡觀察顯示,克隆性 L6565 細胞具有輪廓分明的細胞核,且細胞質中含有大量細胞器以及 A 類和 C 類病毒顆粒。 這些細胞中,致癌基因 c-myc 和 c-fos 均呈現過度表達。L6565 細胞克隆是一種含有 RNA 病毒的淋巴母細胞性白血病幹細胞系。該細胞系已通過本文庫的支原體檢測。

L6565 細胞系的意義在於,它為生命科學與生物技術領域的研究提供了標準化的實驗細胞資源及相關技術支援。這些細胞對於理解白血病的分子機制至關重要,特別是病毒顆粒及致癌基因表達在白血病發生過程中的作用。 此外,該細胞系亦是藥物測試與開發的寶貴工具,使研究人員得以探索治療白血病及其他相關疾病的潛在治療策略。

05Handling and culture

Culture medium
DMEM:Ham's F12(1:1),重量比:3.1 g/L 葡萄糖,重量比:2.5 mM L-谷氨酰胺,重量比:15 mM HEPES, w: 0.5 mM 丙酮酸鈉,w: 1.2 g/L NaHCO₃(Cytion 產品編號 820400a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% FBS、0.005 mg/mL 胰島素、0.01 mg/mL 人類轉鐵蛋白、0.1 mM 乙醇胺、0.1 mM 磷酸乙醇胺、 25 nM 硒、500 nM 氫化可的松、0.005 mM 福斯可林、牛腦下垂體萃取物(每毫升含 0.15 毫克蛋白質)
Subculturing
透過移液管上下吸放,輕柔地將燒瓶中的細胞懸浮液均質化,然後取一份具代表性的樣本,以測定每毫升的細胞密度。使用新鮮培養基將懸浮液稀釋至細胞濃度為 5 × 10⁵ 個細胞/毫升,並將調整後的懸浮液分裝至新的燒瓶中,以供進一步培養。
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 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.

  7. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth.

  8. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.

06Quality control and cryopreservation

Sterility

透過基於 PCR 的檢測及基於發光原理的支原體檢測方法,排除支原體污染的可能性。

為確保無細菌、真菌或酵母菌污染,每日均會對細胞培養物進行目視檢查。

Freeze medium
作為冷凍保存培養基,我們使用完全生長培養基(含 FBS)+ 10% DMSO 以確保解凍後的存活率,或使用 CM-1 (Cytion 型號 800100),該培養基含有經優化的滲透保護劑和代謝穩定劑,可提升細胞恢復率並減輕冷凍誘導的壓力。
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。
