磺化Cy3.5(sulfo Cyanine 3.5; sulfo Cy3.5)是一種發(fā)紅色熒光的花青素類熒光染料。磺化Cy3.5是磺化修飾過的Cy3.5，水溶性好，它在顯影時可以用561nm或者594nm的激光束激發(fā)然后用 Texas Red? 或相似的濾片觀察，所以也是一種非常常用的標記染料?；腔疌y3.5可以用來標記蛋白，抗體，多肽,核酸分子，納米粒等。

磺化Cy3.5水溶性非常好，可在水相標記反應體系中直接使用，不需要有機溶劑助溶，特別適合標記對有機溶劑敏感的生物分子。另外由于強水溶性加染料分子本身帶電荷，磺化Cy3.5標記到生物分子表面后不會引發(fā)疏水性聚集，提高熒光標記產(chǎn)物的穩(wěn)定性。

炔烴(alkyne)是常用生物標記基團。通過銅催化點擊化學反應(Copper-catalyzed azide–alkyne cycloaddition, CuAAC)，炔烴可以和疊氮(azide)生成穩(wěn)定的生物鏈接(bioconjugate)。點擊化學反應效率很高，可在水相中(也可有機相)快速完成，即便在低濃度(μM)下。點擊化學反應技術(shù)發(fā)展很成熟，各種相關(guān)試劑商業(yè)易得，各種生物標記應用廣泛。

Cy3.5標記后的產(chǎn)物Ex/Em是591nm/604nm。和它具有相似熒光特性的染料包括Texas Red?，Alexa Fluor 594, BODIPY? TR, DyLight 594等。
