Improved 488 dye to label with reduced copper concentrations
This special green-fluorescent dye enables advanced click reaction kinetics due to molecular structure that works as a strong copper-chelating system allowing the formation of a strong and active copper complex, that makes AZDye 488 Azide Plus the reactant and the catalyst in the CuAAC reaction. Therefore, less amount of copper can be used achieving the same reaction efficiency. This effect can be crucial e.g. when copper sensitive enzyme or biomolecules shall be labeled. Once clicked to a biomolecule fluorescence detection is identical to FAM, FITC, or any other alternative dye.
