  Coumarin–fluorescein pair as a new donor–acceptor set for fluorescence energy transfer study of DNA

  摘要：

  A method for introduction of the 2'-coumarin labeled nucleoside as a fluorescence energy donor into DNA duplexes has been described. Efficient FRET occurs between the coumarin-fluorescein pair in DNA owing to the high quantum yield of the donor. The present donor-acceptor pair may be useful as FRET indicator of DNA structures in solution, (C) 2000 Elsevier Science Ltd. All rights reserved.
