CY5.5 hydrazide|羰基染料Cy5.5酰肼|CY5.5HZ
Cy5.5 hydrazide是含羰基的近紅外活性染料。酰肼可以與一些羰基化合物迅速反應(yīng)，例如醛類和酮類，并能形成穩(wěn)定的腙。該反應(yīng)可用于標(biāo)記偶聯(lián)物的制備。
生物分子中的羰基基團(tuán)可以在氧化應(yīng)激或蛋白質(zhì)的脫氨基作用之后自發(fā)的形成?；蛘?，醛基可以通過糖蛋白分子糖殘基的高碘酸氧化特異生成，例如抗體?？贵w可以被高碘酸鈉氧化，并且可以被Cy5.5酰肼標(biāo)記，從而形成Cy5.5酰肼標(biāo)記的抗體。由于抗體中的糖殘基遠(yuǎn)離可變的表位結(jié)合位點(diǎn)，用這種方法標(biāo)記抗體是很理想的。
Cy5.5是一種近紅外熒光團(tuán)，是Cy5®的類似物。它特別適用于對(duì)低熒光背景有要求的應(yīng)用。該染料的吸收和發(fā)射波長(zhǎng)具有*的組織穿透力，所以Cy5.5可用于體內(nèi)近紅外成像應(yīng)用。
