PSP pacDNA, is prepared using solid-phase and graft-onto methodologies. Consisting of a polyphosphodiester backbone and poly(ethylene glycol) side chains, the PSP pacDNA suppresses non-specific interactions with the cell and improves the plasma pharmacokinetics of the aptamer. Combined with a thrombin-binding aptamer, the PSP pacDNA produces a pronounced anticoagulation effect in vivo.
