CY5.5 hydrazide,羰基染料Cy5.5酰肼
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,例如醛類和酮類,并能形成穩定的腙。該反應可用于標記偶聯物的制備。
生物分子中的羰基基團可以在氧化應激或蛋白質的脫氨基作用之后自發的形成。或者,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。抗體可以被高碘酸鈉氧化,并且可以被Cy5.5酰肼標記,從而形成Cy5.5酰肼標記的抗體。由于抗體中的糖殘基遠離可變的表位結合位點,用這種方法標記抗體是很理想的。
Cy5.5是一種近紅外熒光團,是Cy5®的類似物。它特別適用于對低熒光背景有要求的應用。該染料的吸收和發射波長具有*的組織穿透力,所以Cy5.5可用于體內近紅外成像應用。
