ENZO熱銷產(chǎn)品——TOTAL-NUCLEAR-ID® green/red nucleolar/nuclear detection kit核仁／細(xì)胞核檢測試劑盒（綠色／紅色）

ENZO的TOTAL-NUCLEAR-ID® green/red nucleolar/nuclear detection kit包含兩種專有染料，適用于同時(shí)對細(xì)胞核和核仁進(jìn)行活細(xì)胞染色。這些染料可以檢驗(yàn)由細(xì)胞周期和核糖體發(fā)生等生物過程引起的細(xì)胞內(nèi)分布、運(yùn)輸和定位的核仁動(dòng)態(tài)變化。該試劑盒與大多數(shù)熒光檢測系統(tǒng)兼容，包括常規(guī)和共聚焦熒光顯微鏡，以及高內(nèi)涵篩選（HCS）平臺。TOTAL-NUCLEAR-ID® green/red nucleolar/nuclear detection kit專門設(shè)計(jì)用于觀察活細(xì)胞中的核仁和細(xì)胞核，潛在應(yīng)用包括監(jiān)測受損核糖體的生物生成、抑制轉(zhuǎn)錄、細(xì)胞周期動(dòng)力學(xué)和細(xì)胞應(yīng)激，以及核仁蛋白的分布、運(yùn)輸和動(dòng)力學(xué)，病毒蛋白的分布，并可能有助于識別癌癥細(xì)胞。

產(chǎn)品特點(diǎn)

● 同時(shí)對活細(xì)胞中的核仁和細(xì)胞核染色

● 高耐光漂白性和抗淬滅，即使在長時(shí)間觀察后也能確保強(qiáng)烈一致的熒光信號

● 已驗(yàn)證在活細(xì)胞成像應(yīng)用中的實(shí)用性，對核仁擾動(dòng)劑的治療有適當(dāng)?shù)姆磻?yīng)性

● 生產(chǎn)嚴(yán)格，以控制和消除非特異性結(jié)果

實(shí)例分析

● NUCLEOLAR-ID®綠色檢測試劑（A）和NUCLEOR-ID®紅色檢測試劑（B）的吸收和發(fā)射光譜

● 用NUCLEOLAR-ID®綠色檢測試劑染色的細(xì)胞在核仁內(nèi)顯示出最大的熒光信號，在整個(gè)細(xì)胞核和細(xì)胞質(zhì)中顯示出微弱的熒光（A）。當(dāng)用低劑量放線菌素D處理細(xì)胞時(shí)，觀察到核仁染色丟失（B）。與較弱的細(xì)胞質(zhì)染色相比，使用NUCLEOLAR-ID®紅色檢測試劑進(jìn)行反染色有助于突出核仁。

● 用TOTAL-NUCLEAR-ID® Green/Red Nucleolar/ Nuclear Detection Kit對U2OS活細(xì)胞進(jìn)行染色，通過熒光顯微鏡觀察細(xì)胞核（紅色）和核仁（黃綠色）的染色結(jié)果。作為一種RNA染料，NUCLEOLAR-ID®綠色染料也顯示出一些細(xì)胞質(zhì)染色，但NUCLEOR-ID®紅色染料有助于在高亮顯示的紅色細(xì)胞核熒光信號范圍內(nèi)，將核仁明確識別為綠色熒光信號。

● U2OS細(xì)胞中染色為紅色的細(xì)胞核和染色為綠色的核仁的3D重建
