In various embodiments, the present invention provides fluorescent dyes that are linked to another species through an amino acid or peptide linker. In an exemplary embodiment, the dye is linked to a polyphosphate nucleic acid through an amino acid or peptide linker. These conjugates find use in single molecule DNA sequencing and other applications. In various embodiments, the dye moiety is a cyanine dye. Cyanine dyes that are highly charged, such as those including multiple sulfonate, alkylsulfonate, carboxylate and/or alkylcarboxylate moieties are examples of cyanine dyes of use in the compounds of the invention.
在各种实施方式中,本发明提供了通过氨基酸或肽连接剂与另一物种连接的荧光染料。在一个示例实施方式中,该染料通过氨基酸或肽连接剂与多聚磷酸核酸连接。这些结合物可用于单分子DNA测序和其他应用。在各种实施方式中,染料部分是一种靛蓝染料。高度带电的靛蓝染料,例如包括多个磺酸盐,烷基磺酸盐,羧酸盐和/或烷基羧酸盐基团的靛蓝染料,是本发明化合物中使用的靛蓝染料的例子。
