Heteroaryl cyanine dyes bearing sulfonic acid substituents are of use in various assays, including single molecule nucleic acid sequencing. Exemplary heteroaryl cyanines dyes include or more reactive functional group, which is of use to covalently conjugate the cyanine dye to a carrier molecule. An exemplary carrier molecule is an analyte molecule or other molecule of interest, for example, a nucleotide oligophosphate.
