01General information
- Description
15p-1 細胞是一種源自小鼠(Mus musculus)的哺乳動物細胞系,專門用於研究細胞對類固醇激素的反應。這些細胞源自小鼠睪丸組織,對雄激素具有獨特的敏感性,因此在內分泌學及癌症研究中具有特別重要的價值。 15p-1 細胞系會表達雄激素受體(AR),因此可用於研究雄激素對基因表達、細胞生長及分化過程的影響。
15p-1 細胞的特色在於,可用於探索受雄激素影響的分子途徑,以及其在前列腺癌等疾病中的作用。該細胞系提供受控的體外環境,用以剖析雄激素與其細胞受體之間的相互作用,有助於深入理解正常生理狀態與病理狀態。 此細胞系對於篩選針對雄激素相關路徑的潛在藥物亦至關重要,有助於開發治療策略。

05Handling and culture
- Culture medium
- DMEM,含 4.5 g/L 葡萄糖、4 mM L-谷氨醯胺、3.7 g/L NaHCO₃ 及 1.0 mM 丙酮酸鈉(Cytion 產品編號 820300a)
- Incubation atmosphere
37°C,5% CO₂,加濕環境。
- Supplements
- 在培養基中加入 10% 的胎牛血清(FBS)
- Dissociation reagent
- Accutase
- Subculturing
- 首先,將附著細胞中的舊培養基移除,並用不含鈣和鎂的PBS洗滌細胞。T25培養瓶需使用3-5毫升PBS,T75培養瓶則需使用5-10毫升。 接著,用 Accutase 完全覆蓋細胞,T25 培養瓶使用 1-2 毫升,T75 培養瓶則使用 2.5 毫升。將細胞於室溫下孵育 8-10 分鐘,使其脫落。 孵育後,將細胞與 10 毫升培養基輕柔混合以使其重新懸浮,然後以 300xg 離心 3 分鐘。棄去上清液,將細胞重新懸浮於新鮮培養基中,並轉移至已預先加入新鮮培養基的新培養瓶中。

- 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。
