Cyanine5.5 hydrazide,CY5.5酰肼染料

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(guò)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。
