pubpic2017thirunavukarasuWe report the selection and characterization of 2′-F purine aptamers that bind human neutrophil elastase (HNE) with reasonable affinity. The 2′-F substituents are found to facilitate the selection of specific interactions, and we demonstrate than only a few can optimize properties far beyond simple nuclease resistance.
