Abstract
We report the use of modified RNA, in which the 2'-OH group of pyrimidines is replaced by a 2'-amino (2'-NH2) group to identify high affinity ligands specific for human neutrophil elastase (HNE) by in vitro selection. Compared to unmodified RNA the 2'-NH2-modified RNA ligands show enhanced stability in human serum and urine. Use of RNase T1 cleavage data in the presence of K+ and Li+ ions suggests that the modified RNA ligands selected for HNE form an intermolecular G-quartet structure.Entities:
