01General information

Description

NU-DUL-1 是一種源自成人患者的人類彌散性大 B 細胞淋巴瘤(DLBCL)細胞系。該細胞系因其在研究非霍奇金淋巴瘤(特別是侵襲性彌散性大 B 細胞亞型)的分子與細胞機制方面具有實用價值而備受矚目。 NU-DUL-1 細胞展現出 DLBCL 的典型特徵,包括異常的 B 細胞分化及失調的訊號傳導路徑,使其成為淋巴瘤研究中極具參考價值的體外模型。

NU-DUL-1 細胞以懸浮方式生長,呈現淋巴母細胞樣細胞典型的圓形單細胞形態。它們攜帶常與彌漫性大B細胞淋巴瘤相關的遺傳異常,為探究致癌訊號傳導路徑、藥物抗性機制及潛在治療標靶提供了重要工具。 研究人員常利用 NU-DUL-1 細胞來探究化療藥物與單克隆抗體的療效,以及針對性治療的分子反應。

由於該細胞系保留了與免疫逃逸及與腫瘤微環境相互作用相關的特徵,因此非常適合用於腫瘤免疫學研究。NU-DUL-1 細胞系為臨床前研究提供了一個穩健的平台,有助於深入了解 DLBCL 的生物學特性,並促進針對此種侵襲性淋巴瘤亞型的創新治療策略開發。

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。
