01General information

Description

L1210 細胞系是一種特徵已充分闡明的鼠源性淋巴細胞白血病模型,最初源自一隻罹患淋巴細胞白血病的小鼠。由於其生長特性具侵襲性且增殖能力強,該細胞系在癌症研究中被廣泛應用。 L1210 細胞常被應用於白血病病理機制研究、化療藥物測試,以及探索癌細胞存活與增殖背後之分子機制。

L1210 細胞在體外生長迅速且能維持懸浮培養狀態,使其成為體外檢測與體內實驗(特別是在同基因小鼠模型中)的理想選擇。該細胞系對多種化療藥物的反應性,使其成為抗白血病藥物臨床前篩選的寶貴工具。 研究人員常利用 L1210 細胞來研究藥物抗性機制、評估新型治療化合物,以及探究細胞對 DNA 損傷劑的反應。

此外,L1210 細胞系亦作為理解白血病免疫反應的模型,有助於釐清白血病細胞與宿主免疫系統之間的相互作用機制。這包括腫瘤免疫學、細胞因子產生,以及免疫治療方法療效等相關研究。 總體而言,L1210 細胞系仍是白血病研究中至關重要的資源,為癌症生物學及治療方法的開發做出貢獻。

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.

07Quality 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。
