Fluorescent cyanine and squaraine dyes are described that can be conjugated to analyte molecules of interest such as peptides, proteins, nucleic acids, RNA, DNA, carbohydrates, polymers aid small molecules via a sulfonyl or sulfonamide substituent. The new dyes are made via a novel cyanine dye activation procedure that converts the normally stable, water solubilizing sulfonate substituents into a reactive sulfonyl halides. The sulfonyl halides may be directly conjugated to analytes or can be further converted to more stable reactive sulfonamide handles or to water soluble sulfonamides. The general structure of the new dyes is given below where the central linker is an unsaturated carbon chain or an unsaturated chain containing a squaraine moiety.
描述了可以与感兴趣的分子(如肽、蛋白质、核酸、RNA、DNA、碳水化合物、聚合物和小分子)结合的荧光青霉素和方酮染料,通过磺酰基或磺酰胺取代基。这些新染料是通过一种新颖的青霉素染料活化程序制备的,该程序将通常稳定的水溶性磺酸盐取代基转化为具有反应性的磺酰卤化物。这些磺酰卤化物可以直接与分子结合,也可以进一步转化为更稳定的反应性磺酰胺手柄或水溶性磺酰胺。新染料的一般结构如下,其中中心连接物是不饱和碳链或含有方酮基团的不饱和链。
