Cy3-DBCO,1782950-79-1,近紅外熒光染料

DBCO‐Cy3 is an azide‐reactive fluorescent dye that is well suited for detection and labeling of chemically, enzymatically, or metabolically azide‐modified biopolymers or peptides. The DBCO group reacts with an azide to produce a stable triazole (Figure 1), which is also referred to as the Cu(I)‐free or strain‐promoted click reaction.
