Background

EDANS (1,5-EDANS) is a novel and quenched fluorogenic substrate for assaying retroviral protease by resonance energy transfer (RET)[1].

The peptide sequence of EDANS is derived from a natural processing site for HIV-1 PR[1].Incubation of recombinant HIV-1 PR with the fluorogenic substrate resulted in specific cleavage at the Tyr-Pro bond and a time-dependent increase in fluorescence intensity that was linearly related to the extent of substrate hydrolysis[1].
