LANCE TR-FRET

OF

LANCE® (Lanthanide Chelate Excite) TR-FRET technology combines the benefits of Time Resolved Fluorescence (TRF) with those of Förster Resonance Energy Transfer (FRET) in a simple, highly-sensitive, and highly reproducible assay platform for detection, quantitation and screening in microplate format.

The use of long-lifetime fluorescent lanthanide chelates, rather than other fluorophores, allows for a delay in measurement between excitation and emissions, which occur simultaneously in standard fluorometric assays. Furthermore, FRET detection utilizes energy donor and energy acceptor fluorophore labels in solution to create a no-wash detection assay. By combining the benefits of TRF and FRET, LANCE TR-FRET offers a multitude of benefits over standard fluorometric detection:

  • Homogeneous assay format (no wash steps, no separation steps)
  • Reduced background leading to better S:B
  • Large Stoke’s shift
  • Wider dynamic range
  • Extended signal stability
  • Increased sensitivity. Lower detection limits of 10 pg/mL compared to 100 pg/mL for standard fluorometric detection
  • Faster time to results

From biomarker detection assays, to cAMP/GPCR studies, to kinase and epigenetic assays, our LANCE® and LANCE Ultra TR-FRET assays are sure to save you time and hassle.
