The Chemistry of C-Branched Spermine Tethered Oligo-DNAs and Their Properties in Forming Duplexes and Triplexes

Abstract
The first synthesis of 2′-, 5′- and centrally tethered C-branched spermine oligo-DNAs directly on the solid-support as well as their ability to stabilise DNA duplexes and triplexes are reported.
