01General information

Description

WIL2-S 是一種源自外周血淋巴細胞,並經愛潑斯坦-巴爾病毒(EBV)感染而永生化的人類 B 淋巴母細胞樣細胞系。 該細胞系源自一名健康的成年捐贈者,並展現出 EBV 轉化 B 細胞的典型特徵,包括懸浮生長、表達 B 細胞表面標記物,以及在標準淋巴細胞培養基中穩定增殖。 作為一種非腫瘤來源、經 EBV 使之不老化的淋巴母細胞系,WIL2-S 廣泛用作免疫學、基因毒性及 DNA 修復研究的參考模型。

由於 WIL2-S 具有穩定的核型以及對 DNA 損傷劑的反應特徵明確,因此已被廣泛應用於細胞遺傳學和致突變性檢測,特別是在微核和染色體不穩定性測試中。 該細胞系具備完善的 DNA 修復途徑,並在評估氧化壓力、輻射誘導損傷及化療致基因毒性的研究中,作為對照組使用。其淋巴細胞起源及可重複的生長特性,使其適合在受控的實驗條件下,體外評估破裂基因效應和非整倍體效應。

由於 WIL2-S 並非源自惡性腫瘤,而是由 EBV 使正常 B 細胞系永生化而來,因此它提供了一個重要的基準模型,用於區分癌症特異性分子改變與一般的淋巴細胞反應。 研究人員通常將此細胞系用作非轉化參考模型,應用於基因組穩定性、免疫細胞訊號傳導以及細胞壓力反應機制等研究中。

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。
