生物活性

Dabcyl-KTSAVLQSGFRKME-Edans TFA is a fluorogenic peptide. Dabcyl-KTSAVLQSGFRKME-Edans TFA is used as the substrate to measure the enzymatic activities of protease forms. Dabcyl-KTSAVLQSGFRKME-Edans TFA has the potential for study 2019-nCoV (COVID-19) infection[1][2][3].

体外研究
(In Vitro)

Recombinant 3CLpro is expressed in Pichia pastoris GS115 as a 42 kDa protein that displays a Km of 15 μM with Dabcyl-KTSAVLQSGFRKME-Edans TFA as substrate[1].
The Dabcyl-KTSAVLQSGFRKME-Edans TFA fluorogenic peptide is used as the substrate and the enhanced fluorescence due to cleavage of this substrate catalyzed by the protease is monitored at 538 nm with an excitation wavelength of 355 nm using a fluorescence plate reader[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

生物活性

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

体外研究
(In Vitro)

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].
