EQ1 NHS ester Amin-reaktiver Quencher-Farbstoff
EQ1 NHS ester

Amine-reactive quencher dye has a broad visible absorption but no detectable fluorescence emission in fluorescence resonance energy transfer (FRET) applications.


  • Commonly used in molecular biology FRET applications to quench fluorophores
  • NHS ester quencher dye can be conjugated to amine-labeled probes
  • Enable multiplexing of probes with the use of different reporter-quencher dye pairs
  • Compatible with most common commercially available fluorophores


EQ1 NHS ester is an amine-reactive quencher dye. It has a broad visible absorption but no detectable fluorescence emission, making it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications.


It can be used to quench reporter dyes: FAM, Cy2, TET, JOE, VIC, HEX, Cy3, NED, TAMRA, Cy3.5, ROX, Texas Red, Quasar® 570, CAL Fluor® Gold 540, CAL Fluor® Orange 560, CAL Fluor® Red 590, CAL Fluor® Red 610, Alexa Fluor® 430, Alexa Fluor® 488, Alexa Fluor® 532, Alexa Fluor® 546, Alexa Fluor® 555, Alexa Fluor® 568, Alexa Fluor® 594, DyLight® 488, DyLight® 550, DyLight® 594, ATTO 488, ATTO 520, ATTO 532, ATTO Rho6G, ATTO 550, ATTO 565, ATTO Rho11, ATTO 590, ATTO 594.
