Synthesis scale

Although EDANS/DABCYL and MCA/DNP are used to develop a variety of FRET probes, their short absorption wavelengths and low extinction coefficients have limited their use in the development of sensitive fluorogenic probes. QXL™ dyes are great choices for you to eliminate these limitations. 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.

QXL™ 570 is proven to be the best quencher for TAMRA. QXL™ 670 is a good quencher for Cy5 fluorophores. In summary, our QXL™ dyes have the following advantages: - Most Powerful: enable you to explore the FRET potentials that might be impossible with other quenchers.
- Versatile Reactive Forms: convenient for self-constructing your desired FRET biomolecules.
- A Complete Set of Dyes: to perfectly match your desired fluorescent donors.
- Enhanced Value: competitive price with the best performance.
