| abstract |
The invention provides an asymmetric cyanine dye compound having the structure including substituted forms thereof, wherein, at least one of R<SUB>1 </SUB>and R<SUB>2 </SUB>is linking group, X is O, S, or Se, and n ranges from 0 to 2. The invention further provides reporter-quencher dye pairs comprising the asymmetric cyanine dyes, dye-labelled polynucleotides incorporating the asymmetric cyanine dyes, and hybridization detection methods utilizing the dye-labelled polynucleotides. |
