01General information

Description

Ramos 細胞系是從一名罹患伯基特淋巴瘤的 3 歲男童腹水中建立而來,是免疫學研究中至關重要的資源。 該細胞系以分泌 IgM 為特徵,對於 B 細胞表面抗原的分析、細胞毒性藥物測試、突變分析以及凋亡機制的探索,皆具有無可替代的價值。

RAMOS 細胞呈現淋巴母細胞樣形態,並以其在體外強勁的生長能力而聞名。它們在與 B 細胞發育、功能及惡性病變相關的研究中尤為寶貴,包括 B 細胞受體(BCR)訊號傳導路徑、基因表達,以及正常 B 細胞轉變為惡性細胞的機制研究。

由於其 B 細胞譜系背景,這些細胞亦常被用於抗體生產研究,使研究人員得以探索 B 細胞對各種抗原的反應及隨後的抗體生成。RAMOS 細胞還被應用於藥物開發與毒性研究中。其對各種化療藥物的敏感性,使其成為新癌症療法臨床前評估中不可或缺的工具。

值得注意的是,Ramos 細胞系為 EBV 陰性,為研究不受愛潑斯坦-巴爾病毒(EBV)影響的伯基特淋巴瘤提供了基準模型。

總而言之,Ramos 細胞系是研究 B 細胞生物學與伯基特淋巴瘤的寶貴資源,對於探索 B 細胞發育、惡性轉變、抗體產生以及新型癌症療法療效至關重要。

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。
