  • Binding
  • Fluorescence anisotropy measurements reveal almost a 20-fold increase in HU binding affinity for the A-tract and non-A-tract duplex relative to a random linear duplex (Ka= 6.1 /mM vs. 0.33 /mM). (jbsdonline.com)
  • distance
  • Peptide main chain was stretched by increase in hydrophilicity, and the distance between the fluorescence dye and quencher increased. (nii.ac.jp)
