EDANS, sodium salt 5 - [(2 - aminoethyl)amino]naphthalene - 1 - sulfonic acid, sodium salt
EDANS is one of the most popular donors for developing FRET-based nucleic acid probes and protease substrates. EDANS is often paired with DABCYL or DABSYL in FRET-based probes. Its fluorescence is environment-sensitive.
