Double stranded DNA discrimination by di-pyrene modified γ-cyclodextrin
摘要:
Neutral fluorescent active di-pyrene modified gamma-cyclodextrin (1) was synthesized in order to discriminate with single and double strand DNA (ssDNA and dsDNA, respectively) with high selectivity. The binding and selectivity of 1 for dsDNA was indicated by increase of the fluorescent intensity in an addition of dsDNA. On the other hand, an increase of fluorescent intensity of 1 was not recognized in an addition of ssDNA. (C) 2010 Elsevier Ltd. All rights reserved.
