摘要
Herein, Forster resonance energy transfer (FRET) was used to investigate the oligomerization of mammalian metallothionein (MT) isoform MT-1. A FRET system was developed based on a highly fluorescent ZnCd quantum dot (QD) and cyanine 3 (Cy3) as a powerful tool to probe small distance changes between acceptor and donor fluorophores in nanometer range. In this study, the water-soluble 450-nm emitting ZnCd QDs as donor and 570-nm Cy3 as acceptor were covalently conjugated with MT-1. MetallothioneinMT1 forms dimers (as well as higher oligomers) upon storing under aerobic conditions. These dimers/oligomers were investigated using capillary electrophoresis (CE) coupled with fluorescence detection.
