Sulfo-Cy3 NHS，水溶性Cy3活性酯熒光染料

    水溶近紅外染料sulfo-Cyanine7，是胺類活性琥珀酸亞胺酯。Sulfo-Cyanine7是Cy7?熒光團(tuán)的的改良衍生物，量子產(chǎn)率提高20%，并具有更好的耐光性。該染料尤其適用于NIR成像應(yīng)用。近紅外熒光染料利用了生物組織在特定的波長(zhǎng)范圍里的透明度。這種方法是無損傷性的，并允許在活體內(nèi)對(duì)多種已標(biāo)記的生物分子的分布進(jìn)行跟蹤。Sulfo-Cyanine7 NHS ester可以很輕松的標(biāo)記生物分子，如：蛋白質(zhì)。標(biāo)記的分子可以用于后續(xù)多種研究及藥物開發(fā)相關(guān)的實(shí)驗(yàn)。這種染料有很高的水溶解度，尤其適用于痕量蛋白質(zhì)和易變性蛋白質(zhì)的標(biāo)記。需有機(jī)溶劑才能溶解的非磺化的Cyanine7 NHS ester。
