01General information
- Description
TK6 是一種源自一名被診斷為遺傳性球形紅細胞症的 5 歲男童脾臟的淋巴母細胞系。該細胞系最值得注意之處在於其胸苷激酶(TK)基因座呈雜合狀態,這正是其能應用於遺傳學研究的重要基礎。 TK 基因座上的雜合性使 TK6 細胞能作為檢測正向突變的敏感模型,為致突變性測試及遺傳毒理學研究提供了一個穩健的平台。
該細胞廣泛應用於旨在定量檢測三個位點正向突變的試驗中,其中包括 tk 位點對三氟胸苷的抗性。此項能力使 TK6 成為製藥及化學產業中評估新化合物致突變潛力的無價工具。 該細胞系的獨特遺傳背景及其與疾病的相關性,使其成為一項關鍵資源,可用於在受控環境下深入理解突變過程,並評估化學物質暴露所產生的細胞遺傳學效應。

- Thawing and culturing
Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit.
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.
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.
Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening.
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.
Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium.
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.
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。

08Legal and safety
- Safety precautions
- 若計劃將低溫試管存放在液態氮中以供日後解凍,必須嚴格遵守相關安全措施。 必須穿戴適當的防護手套和防護服,且在將冷凍樣本移入或移出液氮罐時,必須佩戴口罩或安全護目鏡。此舉旨在降低因取出時冷凍試管可能發生爆炸而導致受傷的風險,此類爆炸可能造成尖銳碎片飛濺。
- Warranty
在 Cytion,我們對產品的品質與存活率提供保障。 我們保證,自本公司設施出貨後 60 天內,我們的細胞在培養開始時仍具存活能力。 我們保證所有材料均符合 分析證明書及/或產品說明書中所載的規格。
