Traditionally antibodies have been considered the gold standard of targeting ligands, able to specifically target desired cellular targets with high affinity. Aptamers, small nucleic acid ligands, are targeting ligands with antibody-like affinities and specificities at a fraction of the size. Our lab selects novel aptamers against different disease targets and utilizes the unique properties of the aptamers to better detect, image and treat diseases. This involves the use of both in vitro biological aptamer selection techniques as well as oligonucleotide synthesis methods. Our ultimate goal is to develop new clinically relevant therapeutic and imaging agents to improve patient outcomes.
