CY7 NHS, Cyanine7 NHS ester
胺類活性染料，近紅外熒光染料，Cy7@的改進(jìn)的類似物。近紅外熒光素可以被用來利用生物組織的近紅外窗口。在這個(gè)光譜區(qū)域，高度增強(qiáng)的組織透明度使得活體成像成為可能。該染料可用于制備CY7標(biāo)記的生物分子來進(jìn)行后續(xù)試驗(yàn)，如活體研究及藥物開發(fā)相關(guān)實(shí)驗(yàn)。Cy7的特殊結(jié)構(gòu)加固了中心聚亞甲基（polymethyne）鏈的穩(wěn)定性。這種增強(qiáng)的分子結(jié)構(gòu)會(huì)使其量子產(chǎn)率較其母結(jié)構(gòu)提供20%，因此它的熒光強(qiáng)度會(huì)更大。
該試劑在標(biāo)記時(shí)需要共溶劑有機(jī)溶劑。水溶Cy7 NHS ester可以用于蛋白NIR標(biāo)記。
