trFluor™ Eu (Ex/Em = 346nm / 617 nm) is a fluorophore with large Stokes shifts and an extremely long emission half-live. It is ideal for applications that require high sensitivity and for time-resolved fluorometry because a delay between excitation and the detection of emission minimizes interference. EU-labeled probes are characterized by a relatively high stability and are often insensitive to quenching. trFluor™ Eu is covalently and randomly conjugated to the target protein.
