  • This special green-fluorescent dye enables advanced click reaction kinetics. 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.
