Highly efficient FRET leads to important enhancements for homogeneous immunoassays. By using the novel phosphorescent dye EuLH and BHQ-10 as a donor-acceptor pair, the FRET efficiency increases to >99.5 %, leading to significantly improved signal-to-background ratio, precision and linear range. The phosphorescence detection enabled full compatibility to serum samples for this fast-responding immunoassay.
