Time-Resolved Forster Resonance Energy Transfer TR-FRET

4 Time-Resolved Forster Resonance Energy Transfer (TR-FRET) 

These assays are based upon the use of a europium or terbium chelate (a transition metal-ligand complex displaying long-lived fluorescent properties) and labeled anti-phosphopeptide or anti-phos-photyrosine antibodies that can bind to phosphorylated peptides. The antibodies are usually labeled
