Legacy Theses & Dissertations (2009 - 2024)
The Thrombin Binding Aptamer (TBA), a short DNA strand with G-quadruplex conformation, binds to Thrombin with high affinity and acts as an inhibitor in the blood clotting. The TBA folds into a G-quadruplex conformation and stabilize the binding toward Thrombin. With this specificity of TBA with Thrombin, our goal is to enhance the binding affinity between them to observe the possibility of developing a new anticoagulant. First modification that we studied was dendrimer linkers which are called Trebler (T) and Long Trebler (LT). Those linkers were incorporated at the 5’ end of TBA by using solid phase oligonucleotide synthesis. Second …
