Cy7 Picolyl Azide|Cy7-吡啶甲基疊氮
Cy7 Picolyl Azide is an advanced fluorescent probe that incorporates a copper-chelating motif to raise the effective concentration of Cu(I) at the reaction site. The chelating effect of picolyl azide moiety to raise the effective concentration 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 Cy7 Picolyl Azide instead of conventional Cy7-Azide allows for at least a tenfold reduction in the concentration of the copper catalyst without sacrificing the efficiency of labeling.
In summary, the introduction 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.
