  Nonclassical SNAPFL Analogue as a Cy5 Resonance Energy Transfer Partner

  摘要：

  We have synthesized a new SNAPFL analogue (1) that exhibits a large Stokes shift (78 nm) (abs. 542 nm, em. 620 nm) and a good quantum yield. Because of the large overlap between the emission spectrum of 1 and the absorption spectrum of Cy5, 1 functions well as a fluorescence donor to Cy5 and has been used in FRET-based experiments using estrogen receptor site-specifically labeled with Cy5 and a receptor ligand conjugated to SNAPFL.
