Abstract

original image

A supramolecular tandem assay method has been applied to the determination of D-lysine enantiomeric excesses of up to 99.98 %. In their Full Paper on page 6069 ff., Nau et al. use the cucurbit[7]uril macrocycle to complex a dye and by monitoring the fluorescence change accompanying the enzymatic decarboxylation of the amino acid determine D-lysine enantiomeric excesses. This method has allowed the measurement of nanomolar analyte amounts in microtiter plates and enables potential applications in high-throughput screening and drug discovery.
