R-M-5449	TAMRA Picolyl Azide	TAMRA 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.

This probe is compatible with various excitation sources including mercury arc, tungsten and xenon arc lamps, the 544 nm line of the Helium-Neon laser and the 532 nm green laser line.In addition, the use of TAMRA Picolyl Azide instead of conventional TAMRA 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.	price>
