01General information

Description

BJAB 細胞系於 1973 年由一名被診斷為愛潑斯坦-巴爾病毒(EBV)陰性伯基特淋巴瘤的 5 歲非洲女童建立。 這種特殊的來源對研究至關重要,因為它提供了一個獨特的模型,用於在沒有EBV影響的情況下研究伯基特淋巴瘤——而EBV的影響在許多其他淋巴瘤細胞系中十分常見。BJAB細胞的EBV陰性狀態,使研究人員能夠在排除病毒干擾的情況下,探究導致淋巴瘤發生的遺傳和環境因素。

BJAB 細胞常被用於腫瘤學研究,特別是探索伯基特淋巴瘤的病理生理學,以及測試針對該疾病的治療策略。 該細胞系展現了伯基特淋巴瘤的許多標誌性特徵,包括高增殖率及特有的免疫表型。其遺傳穩定性與強健的培養特性,使其成為用於理解淋巴瘤生物學及評估抗癌藥物療效之體外實驗的寶貴工具。

3 × 105 個細胞/毫升
Fluid renewal
每 3 至 5 天
Post-thaw recovery
請讓細胞有至少 48 小時的時間從冷凍過程中恢復。
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。
