01General information
- Description
SNU-5 細胞系是一種由轉移性病灶建立的人類胃癌模型。其分子異常特徵已獲闡明,特別是涉及 p53 腫瘤抑制基因的異常。 研究顯示,SNU-5 呈現 p53 基因轉錄本的缺失,此結論是根據 Northern blot 分析中未檢測到 p53 mRNA 而得出的。 此缺失現象進一步獲得核糖核酸酶保護試驗(RNase protection assays)及定序分析的支持,結果顯示 SNU-5 雖然在編碼區中未檢測到突變,但完全無法表達該轉錄本,這表明基因沉默可能是由調控或表觀遺傳機制所致,而非結構性突變。
蛋白質體學分析為 SNU-5 的分子特徵提供了更深入的見解。大規模研究已將 SNU-5 納入用於繪製人類癌細胞系蛋白質體圖譜的癌細胞系組中。在此背景下,SNU-5 為整合數千種蛋白質質譜定量數據的資料集做出了貢獻。 這些蛋白質體學數據集已與轉錄組、基因組及表型特徵進行關聯分析,從而提供關於蛋白質表達、轉錄後調控及藥物反應特徵的全面視角。此類數據集使 SNU-5 成為研究胃癌生物學的寶貴模型,特別是在轉移性疾病及 p53 通路失調的背景下。

- 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.
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。

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。
