01General information

Description

EB1 細胞系是一種源自人類的細胞系,由伯基特淋巴瘤的活組織檢查片段及細胞團建立而成。該細胞系最初是在添加 10% 人血清的 Eagle 基礎培養基中培養的。 這種獨特的培養條件促使細胞主要以自由漂浮的單細胞或雙細胞形式生長。EB1 細胞的倍增時間約為 48 小時,凸顯其快速增殖率,這正是淋巴母細胞的標誌性特徵。

形態學上,EB1 細胞呈現均勻且特異的淋巴母細胞變異特徵,表明其源自淋巴組織。該細胞系已被廣泛應用於伯基特淋巴瘤的研究,為淋巴系惡性腫瘤的病理學提供了重要見解。 它作為研究淋巴細胞在各種實驗條件下生物行為的寶貴模型,有助於探索治療靶點並理解淋巴瘤的進展。

Cell type
B 淋巴細胞
Karyotype
染色體頻率分佈 30 個細胞:2n = 46。該細胞系為非整倍體人類女性,其染色體數目接近二倍體範圍。正常染色體 N8、N11 和 N14 呈單體性,其餘常染色體通常呈成對分布。 X 染色體最常呈三體。發現四條標記染色體。其中兩條(標記 M1 和 M3)涉及 N8 號與 N14 號染色體之間的互補易位,此現象與大多數伯基特淋巴瘤細胞系相關。

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。
