title: Investigations of oligodeoxyinosine for triple helix formation.
abstract: The ability of a 17-mer of deoxyinosine to form a triple helix with a (dT)17(dA)17 segment of a 29-mer Watson-Crick duplex was investigated. Under conditions amenable to triple helix formation, (dT)17 showed evidence of complex formation as evidenced by UV melting curves and gel mobility shift assays whereas (dI)17 did not.
