Covalent conjugates of 1,4-bis-phenylazo-benzene and phenylazo-phenazine derivatives as dark quenchers of donor acceptor energy transfer for fluorescence detection of biomolecules and drugs

摘要

The present invention provides a family of dark quenchers, termed Black Hole Quenchers ("BHQs"), that are efficient quenchers of excited state energy but which are themselves substantially non-fluorescent. Also provided are methods of using the BHQs, probes incorporating the BHQs and methods of using the probes.
