Application Note: The Next Step in Near Infrared Fluorescence:IRDye® QC-1 Dark Quencher
19 June 2011

This application note introduces the quencher dye, IRDye QC-1 for use with near-infrared (NIR) applications. IRDye QC-1 is an excellent quencher with essentially no inherent fluorescence and good water solubility, for use in many biological applications. This quencher dye also has the widest available quenching range, with the ability to quench both visible and near infrared fluorophores (~500 nm to ~900 nm).
