Secondary binding sites for triplex-forming oligonucleotides containing bulges, loops, and mismatches in the third strand.
We have used DNase I footprinting to examine the binding of five different 17-mer oligonucleotides to a 53-base oligopurine tract containing four pyrimidine interruptions. Although all the expected triplexes formed with high affinity (K(d) approximately 10-50 nM), one oligonucleotide produced a foot...
