QXL® 490 dyes are the optimized quenchers for EDANS, AMCA and most coumarin fluorophores. Their absorption spectra perfectly overlap with the fluorescence spectra of EDANS and AMCA. This characteristic makes QXL® 490 dyes excellent quenchers for EDANS, AMCA and coumarin fluorophores. QXL® 490 acid can be coupled to amino groups via EDC-mediated reactions.
