The invention provides compounds and compositions of Formulas I-VII, and methods of using the compounds. The compounds can be used to prepare dye conjugates that are uniformly and substantially more fluorescent on proteins, nucleic acids or other biopolymers, than conjugates labeled with structurally similar known carbocyanine dyes. In addition to having more intense fluorescence emission than structurally similar dyes at virtually identical wavelengths, and decreased artifacts in their absorption spectra upon conjugation to biopolymers, the compounds can have greater photostability and/or higher absorbance (extinction coefficients) at the wavelength(s) of peak absorbance than such structurally similar dyes.
该发明提供了公式I-VII的化合物和组合物,以及使用这些化合物的方法。这些化合物可用于制备染料共轭物,其在蛋白质、核酸或其他生物聚合物上比使用结构类似已知碳氰染料标记的共轭物具有更均匀和明显更荧光。除了在几乎相同波长下比结构类似染料具有更强的荧光发射外,并且在与生物聚合物结合时吸收光谱中的伪迹减少,这些化合物在吸收峰波长处可能具有更高的光稳定性和/或更高的吸光度(消光系数)比这些结构类似的染料。
