Cyanine7.5是NIR（近紅外光譜）染料，是長波段的紅外熒光。該疊氮類衍生物用于點擊化學(xué)。
可以標(biāo)記多種生物分子，近紅外熒光染料，是Cy7.5®改進(jìn)的衍生物。標(biāo)記的該熒光染料可以利用NIR組織透明度而進(jìn)行體內(nèi)成像實驗。這種熒光素亦可用于其他熒光類應(yīng)用，尤其當(dāng)需要較低的熒光背景時。
該疊氮染料還有溶于DMSO的溶液形式可供選擇，即用于一般的點擊化學(xué)的標(biāo)記。或者粉劑形式自行標(biāo)記使用。
Cyanine7.5的橋連聚亞甲基鏈的結(jié)構(gòu)特點會使量子產(chǎn)率提高20%，信號更強。
