Up to 40-fold increase of signal intensity, compared to conventional azides, was reported (see Selected References). In addition, the use picolyl azides instead of conventional azides allows for at least a tenfold reduction in the concentration of the copper catalyst without sacrificing the efficiency of labeling, significantly improving biocompatibility of CuAAC labeling protocol. In summary, the introduction of a copper-chelating motif into azide probe leads to a substantial increase in the sensitivity and reduced cell toxicity of CuAAC detection alkyne-tagged biomolecules. This will be of special value for the detection of low abundance targets or living system imaging. AZDye™ 405 is structurally similar and spectrally is almost identical to DyLight® 405, Alexa Fluor® 405, CF® 405S Dye, or any other sulfonated pyrene based fluorescent dyes.
