IRDye® QC-1 Dark Quencher

Non-fluorescent quenching dyes have been used as probes in various application such as: protease activity assays, nucleic acid hybridization, and real-tie PCR. Most of these probes have been used with  visible fluorophores at wavelengths <700 nm. Higher wavelength near-infrared dyes such as IRDYe 800CW couple with IRDye QC-1 developed by Li-COR Biosciences have offer improvement which extended the benefits of fluorescent detection to Western blotting and in vivo imaging and can provide improved performance for cell-based assays, protein microarrays, microtiter plate assays, microscopy, and screening of small molecule libraries
