Descripción

Covidyte™ TF670 is a peptide substrate that can be cleaved by coronavirus proteases. The dark-FRET peptide contains Tide Quencher™ 5 (TQ5) as a quencher and Tide Fluor™ 5 (TF5) as a fluorescent donor on the N-and C-terminals respectively where the fluorescence of TF5 is effectively quenched by TQ5 when the peptide is intact. When the peptide is hydrolyzed by coronavirus proteases, the TF5 fragment generates significantly enhanced fluorescence since its fluorescence is no longer quenched by TQ5. The activity of coronavirus proteases can be effectively monitored by the fluorescence intensity of TF5. Covidyte™ TF670 is a robust high throughput screening tool for searching inhibitors of coronavirus proteases. TQ5-TF5 pair has been proven to an extremely effective FRET pair for developing FRET protease substrates. Comparing to the commonly used EDANS substrates (such as Covidyte™ EN450), the TF670 substrate has much stronger and longer fluorescence that is less interfered by colored compounds that often cause false positive hits.
