Phosphoprotein-Selective Recognition and Staining in SDS-PAGE by Bis-Zn(II)-dipycolylamine-Appended Anthracene

A novel fluorescence detection system using a chemosensor for phosphoprotein in gel electrophoresis analysis has been developed. The system employed bis-Zn(II)-dipycolylamine (Dpa)-appended anthracene as a fluorescent staining dye to carry out convenient and selective detection of phosphoproteins in SDS-PAGE.
