Water-Soluble QXL™ Dyes - Optimized FRET Acceptors Covering the Full Visible Spectrum

Although DABCYL/EDANS and DNP/MCA are used to develop a variety of FRET probes, their short absorption wavelength and low extinction coefficient have limited their use in the development of sensitive fluorogenic probes.

First dark quenchers compatible with protein analysis, QXL™ dyes are great choice to address these limitation: instead of measuring 2 fluorescences, the use of a dark quencher allows one single measurement and maximizes signal/noise ratio.

QXL™ dyes are excellent dark quenchers that are individually optimized to pair with all of the popular fluorescent dyes such as fluoresceins and rhodamines. Our QXL™ series of nonfluorescent dyes cover the full visible spectrum with unusually high efficiency.

We offer the most comprehensive peptide collection, and the possibility to synthetize labelled custom peptides according to your request (contact Nathalie BERVAS, Brand Manager (nathalie.bervas@tebu-bio.com))
