Finderons and methods of their preparation and use

摘要

Disclosed is a finderon having the ability to endonucleolytically cleave a sequence of 3' to 5' linked ribonucleotides. The finderon includes a rigid linker comprising at least one non-nucleotidic unit, flanked by first and second flanking regions of at least four contiguous, covalently-linked nucleotides. At least a portion of each flanking region is complementary to a target region on a substrate RNA molecule. Also disclosed are methods of preparing and using a finderon, and kits including a finderon.
