01General information
- Description
U266 細胞系(亦稱 U-266)是一種人類多發性骨髓瘤細胞系,由一名 53 歲、患有 IgE 型骨髓瘤的男性患者的外周血建立而成。 該細胞系的特徵在於能同時分泌免疫球蛋白輕鏈與重鏈,其中以λ型輕鏈和IgE型重鏈為主。 U266 細胞系表現出典型的 B 淋巴細胞標記,並已被廣泛應用於骨髓瘤生物學的研究,特別是用於理解漿細胞惡性腫瘤的病理生理機制及免疫反應。
U266 細胞在藥物發現與開發中扮演重要角色,為評估抗骨髓瘤藥物的療效提供了可靠的模型。此外,該細胞系亦被用於研究骨髓瘤細胞與骨髓微環境之間的相互作用,這對於理解骨髓瘤的進展及對治療的抗藥性至關重要。 遺傳學研究揭示了 U266 細胞中存在多種染色體異常,這些異常促成了其惡性表型及對凋亡的抵抗力。該細胞系在推動多發性骨髓瘤分子靶向治療的發展方面發揮了關鍵作用。

- Post-thaw recovery
- 解凍後,請讓細胞有至少 24 小時的時間從冷凍過程中恢復。
- 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.
05Quality 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。

07Legal 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。
