TR-FRET

Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) is a special form of resonance energy transfer (FRET) in which long emission fluorophores (lanthanides) are used as donors. The comparison measurement of the two emitted wavelengths over time is calculated for a TR-FRET response. The most common TR-FRET assays include HTRF ® , LanthaScreen ® , LANCE ® , and Transcreener ® ADP2 TR-FRET Red Assay.

TR-FRET detection with BMG LABTECH microplate readers

TR-FRET-based detection can be performed on all BMG LABTECH multi-mode plate readers , for example PHERAstar ® FSX , CLARIOstar ® , and the FLUOstar ® and POLARstar ® Omega . All readers are equipped with a high-intensity xenon flashlamp. Assay -specific filters or Optic Modules yield higher light transmission, specifically select the desired wavelength, and minimze background noise. Moreover, the PHERAstar FSX offers further TRF-dedicated features such as the unique Decay Curve Monitoring and a dedicated TR-FRET-laser .

See some examples of TR-FRET measurements on BMG LABTECH instruments below.
