01General information

Description

OVCAR-5 是一種從未經治療患者的腫瘤中建立的人類卵巢癌細胞系。該細胞系是研究高階卵巢癌生物學的可靠模型,對於探究對鉑類化療藥物之反應,以及化療抗藥性背後的分子機制,尤具價值。 OVCAR-5 已被廣泛應用於藥物臨床前開發及癌症生物學研究。

OVCAR-5 細胞呈現上皮細胞形態,並在標準培養條件下以黏附單層形式生長。與源自化療耐藥患者的其他 OVCAR 系列細胞系不同,OVCAR-5 源自未接受過化療的腫瘤,因此可作為探索腫瘤內在特性的基準模型。 值得注意的是,OVCAR-5 會表達金屬硫蛋白(metallothionein),這是一種與細胞對重金屬及氧化壓力反應相關的蛋白質,但這並不一定會像該系列其他細胞系所觀察到的那樣,賦予對順鉑的抗藥性。 該細胞系的順鉑敏感性特徵與源自化療耐藥患者的細胞系不同,其順鉑 IC50 值為 0.61 μM。

在研究中,OVCAR-5 被用於篩選新型化療藥物、評估標靶療法,以及研究旨在改善卵巢癌治療成效的藥物組合。它亦被用於探索高惡性度卵巢癌的遺傳與表觀遺傳特徵,包括 DNA 損傷修復途徑、訊號傳導網絡及腫瘤微環境。 OVCAR-5 仍是深化對卵巢癌理解及推進其治療的重要工具。

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。
