Triplex formation using oligonucleotide clamps carrying 8-aminopurines

The synthesis and properties of triplex-forming DNA clamps carrying 8-aminopurines are described. The stability of triple helices is enhanced by replacing purine bases with 8-aminopurine residues. These enhanced binding properties are used for the specific capture of polypyrimidine RNA/DNA sequences...

Sumario:The synthesis and properties of triplex-forming DNA clamps carrying 8-aminopurines are described. The stability of triple helices is enhanced by replacing purine bases with 8-aminopurine residues. These enhanced binding properties are used for the specific capture of polypyrimidine RNA/DNA sequences of interest.
