硫代-青色素3.5炔烃，Sulfo-CY3.5 alkyne
磺化Cy3.5(sulfo Cyanine 3.5; sulfo Cy3.5)是一种发红色荧光的花青素类荧光染料。磺化Cy3.5是磺化修饰过的Cy3.5，水溶性好，它在显影时可以用561nm或者594nm的激光束激发然后用 Texas Red? 或相似的滤片观察，所以也是一种非常常用的标记染料。磺化Cy3.5可以用来标记蛋白，抗体，多肽,核酸分子，纳米粒等。
磺化Cy3.5水溶性非常好，可在水相标记反应体系中直接使用，不需要有机溶剂助溶，特别适合标记对有机溶剂敏感的生物分子。另外由于强水溶性加染料分子本身带电荷，磺化Cy3.5标记到生物分子表面后不会引发疏水性聚集，提高荧光标记产物的稳定性。
炔烃(alkyne)是常用生物标记基团。通过铜催化点击化学反应(Copper-catalyzed azide–alkyne cycloaddition, CuAAC)，炔烃可以和叠氮(azide)生成稳定的生物链接(bioconjugate)。点击化学反应效率很高，可在水相中(也可有机相)快速完成，即便在低浓度(μM)下。点击化学反应技术发展很成熟，各种相关试剂商业易得，各种生物标记应用***。
Cy3.5标记后的产物Ex/Em是591nm/604nm。和它具有相似荧光特性的染料包括Texas Red?，Alexa Fluor 594, BODIPY? TR, DyLight 594等。
