5-TAMRA azide

5-TAMRA azide,5-Carboxytetramethylrhodamine azide from ruixi.5-TAMRA Azide (also known as TAMRA azide，isomer 5) is the red-fluorescent probe that 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. It is predominantlyused for detection of terminal alkyne-tagged biomolecules via a copper-catalyzed click reaction(CUAAC). It also reacts with strained cyclooctyne via a copper-free“click chemistry”reactionto form a stable triazole and does not require Cu-catalyst or elevated temperatures.Although the mixed isomers of 5(6)-TAMRA azide is a preferred, routinely used red fluorescent dyefor staining proteins，labeling peptides and nucleotides with TAMRA mixed isomers might be troublesome due to significant signal broadening in HPLC purification. Peptides and nucleotideslabeled with a single isomer TAMRA usually give better resolution in HPLC purification that isoften required in the conjugation processes.
