This article describes the genetically encoded caspase-3 FRET-sensor based on the terbium-binding peptide, cleavable linker with caspase-3 recognition site, and red fluorescent protein TagRFP. The engineered construction performs two induction-resonance energy transfer processes: from tryptophan of the terbium-binding peptide to Tb(3+) and from sensitized Tb(3+) to acceptor--the chromophore of ...

Lanthanide (LnIII) ions were successfully chelated and sensitized with a tripodal ligand. The absolute LnIII-centered emission efficiencies ~3% for both the europium(III) (EuIII) terbium (TbIII) complexes up to 54% cerium(III) (CeIII) complex. differences in quantum yields early lanthanides mid (EuIII TbIII) attributed their d–f f–f nature, respectively. Despite low yield of EuIII complex, comb...

A novel method for determination of trace amounts of tosufloxacin (TFLX) based on electrochemiluminescence (ECL) has been developed. The calibration graphs for TFLX were linear in the range of 5.0 x 10(-11)-3.5 x 10(-7) mol/L, with the detection limit of 1.3 x 10(-11) mol/L. Key factors affecting the determination of TFLX were investigated. TFLX amounts in capsule and serum samples were success...
