产品介绍

IRDye QC-1 NHS Ester

IRDye QC-1 is the first non-fluorescent (dark) quencher compatible with a wide range of visible and near-infrared fluorophores (~500-800 nm). It has the widest available quenching range, so you do not need to carefully match the donor's fluorescence spectrum with the acceptor's absorbance. IRDye QC-1 quenches common fluorophores with >97% efficiency1.

IRDye QC-1 stokes shift and wavelength

Energy that is transferred from the donor (Dem) can be emitted at the acceptor's wavelength (Aem), quenching fluorescence.

For more information, see “Spectral Overlap of IRDye QC-1 Absorption with Common Donor Fluorophores” below.

IRDye QC-1 NHS ester can be used for FRET (fluorescence resonance energy transfer) applications such as protease assays. Recently, it has been paired with IRDye 800CW in optoacoustic studies.
