01General information
- Description
PY8119-GFP 細胞是小鼠 PY8119 乳癌細胞系的螢光標記衍生物,該細胞系源自小鼠模型中的自發性乳腺腫瘤。 親本 PY8119 細胞系通常與基因工程改造的小鼠乳癌模型相關,並用於在同基因背景下一研究腫瘤進展、免疫相互作用及治療反應。 綠色螢光蛋白(GFP)的穩定表達使腫瘤細胞的行為得以直接觀察,便於在體外和體內實時追蹤細胞的增殖、遷移及細胞間相互作用。
GFP 修飾使 PY8119-GFP 細胞特別適合應用於活細胞成像、活體顯微鏡觀察,以及在免疫功能正常的小鼠模型中進行轉移研究。這些細胞保留了親本細胞系的主要特徵,包括具侵略性的生長特性,以及植入同基因宿主時形成腫瘤的能力。 因此,PY8119-GFP 細胞被廣泛用於探究腫瘤與免疫系統的動態互動、評估抗癌療法,以及研究侵襲與擴散的機制。然而,與所有經螢光修飾的細胞系一樣,建議進行仔細的驗證,以確保 GFP 的表達不會改變細胞的基線行為。
基因改造:透過複製缺陷型慢病毒轉導進行穩定改造,以表達 ZsGreen1 綠色螢光蛋白報告基因;在嘌呤酶篩選(1–5 µg/mL)下維持為多克隆細胞群。S1/BSL-1 防護等級。

- GMO status details
- GMO-S1: This cell line contains a stably integrated ZsGreen1 green fluorescent protein reporter introduced via replication-incompetent lentiviral transduction. The resulting polyclonal cell population was maintained under puromycin selection (1–5 µg/mL). S1 containment is required. This classification applies only within Germany and may differ elsewhere.

- 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 200 x g for 5 minutes, carefully discard the supernatant containing freezing medium.
Follow the procedure described under Post-Thaw Recovery
07Quality control and cryopreservation
- Freeze medium
- 作為冷凍保存培養基,我們使用完全生長培養基加上 10% 的二甲基亞砜(DMSO),以確保解凍後的細胞存活率達到適當水準。
- 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。

09Legal 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。
