title: Photo-controllable aptamer.
abstract: We have successfully developed a new method for photoregulation of G-quadruplex formation using cis-trans photoisomerization of the photochromic nucleobase (8FV)G. Our photo-controllable quadruplexes can be switched between a very stable quadruplex state and a non-structured state in a straightforward and reversible fashion. We also demonstrated reversibly control binding of a G-quadruplex aptamer to thrombin.
