01General information

Description

SU-DHL-1 是一種從一名被診斷為彌漫性組織細胞性淋巴瘤的兒童之胸腔積液中建立的人類異型大細胞淋巴瘤(ALCL)細胞系。它是首批透過連續培養建立的人類淋巴瘤細胞系之一,其表型與基因型均已經過嚴格的特性分析。 形態學上,SU-DHL-1 保留了原發性腫瘤的特徵,包括含有脂質的大型細胞質空泡。 組織化學研究顯示其具有非特異性酯酶和酸性磷酸酶的活性。與淋巴母細胞樣細胞系不同,SU-DHL-1 對愛潑斯坦-巴爾病毒核抗原(EBNA)呈陰性,且不表達表面免疫球蛋白,這進一步使其有別於源自 B 淋巴細胞的細胞系。

SU-DHL-1 因其染色體轉位 t(2;5)(p23;q35) 而成為 ALK 陽性 ALCL 的標誌性模型,該轉位導致 NPM1-ALK 融合蛋白的表達。 此融合蛋白賦予持續性的酪胺酸激酶活性,並在 ALK+ ALCL 的致癌過程中扮演核心角色。該細胞系隸屬於 LL-100 面板,這是一套經過嚴謹篩選的白血病與淋巴瘤模型集,專用於高通量分子特徵分析。 SU-DHL-1 已被廣泛應用於與 ALCL 相關的致癌訊號傳導、標靶療法開發及轉錄調控研究,使其成為理解和治療此種侵襲性 T 細胞淋巴瘤亞型的重要工具。

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。
