Isolation and identification of aptamers from defibrotide that act as thrombin antagonists in vitro.

Abstract

This study was designed to isolate and identify aptamer sequences, acting as thrombin antagonists, from defibrotide, a single-stranded DNA fraction. Two different aptamers were identified: 5'-GGTTGGATTGGTTGG-3' and 5'-GGTTGGATCGGTTGG-3'. A third aptamer: 5'-GGATGGATCGGTTGG-3' was found in the PCR product from the double-stranded defibrotide precursor. All… (More)
