Cy5.5 Picolyl Azide

Cy5.5 Picolyl Azide is an advanced fluorescent probe that incorporates a copper-chelating motif to raise the effective concen*ration of Cu(I) at the reaction site. The chelating effect of picolyl azide moiety to raise the effective concen*ration of copper at the reaction site is so great that it leads to an increase of signal intensity of up to 40-fold.

In addition, the use of Cy5.5 Picolyl Azide instead of conventional Cy5.5-Azide allows for at least a tenfold reduction in the concen*ration of the copper catalyst without sacrificing the efficiency of labeling.

In summary, the in*roduction of a picolyl moiety into an azide probe leads to a substantial increase in the sensitivity of alkyne detection. This will be of special value for the detection of low abundance targets or where significant increase in signal intensity is desired.
