Fluorescence Quenchers

offers a series of new quenching labels. They are designed to be used as efficient energy acceptors in FRET (Fluorescence Resonance Energy Transfer) applications.

fluorescence quenchers can be coupled to amino and mercapto groups of proteins etc.

Their characteristic properties are:

- strong absorption (high extinction coefficient)
- high photo-stability
- good water solubility
