Cyanine5.5 is a fluorophore with the emission in 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 oligonucleotide synthesizer.
The structure of phosphoramidite functional group that is attached to a secondary carbon atom provides extra stability against Arbuzov rearrangement. This helps maintaining coupling performance over a longer storage time in oligonucleotide synthesizer, compared to phosphoramidites derived of primary alcohols.
