Bivalent aptamers deliver the punch

Chem Biol. 2008 Jul 21;15(7):644-5. doi: 10.1016/j.chembiol.2008.07.004.

Abstract

Aptamers, sometimes termed "chemical antibodies," have been engineered into multimerized versions for therapeutic application. The groups of Gilboa and Sullenger now report the development of a bivalent aptamer-molecular device as a receptor agonist that has the same functional properties, but stronger avidity than a corresponding antibody.
