"Singapore Green": A New Fluorescent Dye for Microarray and Bioimaging Applications.

[摘要]：The authors have synthesized Singapore Green 1 and 2 (I, R = Me and (CH2)5OH resp.), structural hybrids of Tokyo Green and Rhodamine 110. The new dyes are green light-emitting substitutes for 7-aminocoumarin, a blue fluorescent dye widely used in enzymic assays. Singapore Green-conjugated peptide substrates were successfully synthesized and used in microarray-based protease substrate profiling and live-cell imaging expts.
