Quenching resonance energy transfer (QRET): a single-label technique for inhibitor screening and interaction studies

- Homogeneous QRET technology is applicable for wide range of different targets.
- The technology relies on weak interaction between lanthanide chelate and quencher.
- Single-label methodology is easy to use, to convert to new targets.
- Despite the high simplicity, the sensitivity of the assay is preserved.
- QRET is applicable of assays in buffer or in cell membrane or even intact cells.
