01General information

Description

B95-8 細胞系是一種永生化的絨猴 B 淋巴母細胞系,源自棉頂絨猴(Saguinus oedipus)的外周血白細胞。 該細胞系是透過感染愛潑斯坦-巴爾病毒(EBV)而建立的,這是一種常見的 B 細胞不朽化方法。EBV 的存在是 B95-8 細胞系在研究中發揮作用的關鍵,特別是對於與病毒腫瘤學、病毒-宿主相互作用以及 EBV 本身生物學相關的研究。

在病毒學研究中,B95-8 細胞常被用作愛潑斯坦-巴爾病毒的來源。這些細胞能產生具傳染性的病毒顆粒,使其成為 EBV 培養以及需要活性病毒的實驗中不可或缺的工具。 此外,該細胞系在開發針對EBV相關疾病(包括伯基特淋巴瘤和霍奇金淋巴瘤)的疫苗及治療策略方面,發揮了關鍵作用。 這些細胞在研究對 EBV 的免疫反應方面亦具重要意義,因其可用於模擬 B 細胞的轉化,並協助釐清 EBV 誘導腫瘤形成的機制。

05Handling and culture

Culture medium
RPMI 1640,含 2.0 mM 穩定谷氨醯胺,含 2.0 g/L NaHCO₃(Cytion 產品編號 820700a)
Incubation atmosphere

37°C,5% CO₂,加濕環境。

Supplements
在培養基中加入 10% 的胎牛血清(FBS)
Subculturing
透過移液管上下吸放,輕柔地將燒瓶中的細胞懸浮液均質化,然後取一份具代表性的樣本,以測定每毫升的細胞密度。使用新鮮培養基將懸浮液稀釋至細胞濃度為 1 × 10⁵ 個細胞/毫升,並將調整後的懸浮液分裝至新的燒瓶中,以供進一步培養。
Fluid renewal
每週 2 至 3 次
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.

06Quality 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。
