MIXED-BACKBONE OLIGONUCLEOTIDES CONTAINING POPS BLOCKS TO OBTAIN REDUCED PHOSPHOROTHIOATE CONTENT

摘要

Mixed-backbone oligonucleotides POPS blocks have been designed and studied for their target affinity, nuclease stability in vitro and in vivo, Rnase H-activation properties, and their effect on phosphorothioate-related prolongation of partial thromboplastin time, in an effort to have agents with improved antisense activity with reduced phosphorothioate content.
