Cyanine5.5 is a fluorophore with an emission in the far-red range of the spectrum. This dye is useful for multiplex qPCR. Commercial six-channel qPCR instruments often have a channel for Cyanine5.5.
This phosphoramidite can be used for the synthesis of 5'-labeled oligonucleotides by direct labeling in an oligonucleotide synthesizer.
The structure of the phosphoramidite functional group that is attached to a secondary carbon atom provides extra stability against Arbuzov rearrangement. This helps maintain coupling performance over a longer storage time in oligonucleotide synthesizers, compared to phosphoramidites derived from primary alcohols.
