title: "Singapore Green": a new fluorescent dye for microarray and bioimaging applications.
abstract: We have synthesized Singapore Green (SG), a structural hybrid of Tokyo Green and Rhodamine 110. This new dye is a green light-emitting substitute for 7-aminocoumarin, a blue fluorescent dye widely used in enzymatic assays. SG-conjugated peptide substrates were successfully synthesized and used in microarray-based protease substrate profiling and live-cell imaging experiments.
