Stokes Shift Absorption and Emission Peaks for Europium
Stokes shift is the difference between the absorption peak and the emission peak for fluorophores. A larger Stokes shift is always preferred which allows the use of broad excitation and emission filters that do not overlap, which in turn increases brightness and sensitivity. Fluorescent probes of smaller Stokes shift require filters that are very close together and do not include the entire area of the curves, thus reducing efficiency and brightness.

- Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) involves an energy transfer between two fluorophores in close proximity. It is a combination of Time Resolved Fluorescence (TRF) and Forster‘s Resonance Energy Transfer (FRET). This method shows reduced background noise and higher sensitivity and reliability than FRET. In TR-FRET the donor molecule is a Lanthanide metal instead of a fluorescent dye. Lanthanide metals, such as Terbium (Tb) and Europium (Eu), serve as energy donors. Their fluorescence is long-lived and characterized by a large Stokes shift providing a high signal-to-noise ratio.
