Characterization of mismatched DNA hybridization via a redox-active diviologen bound in the PNA-DNA minor groove.

Langmuir : the ACS journal of surfaces and colloids - 9 Apr 2009

Hvastkovs Eli G, Buttry Daniel A

Abstract excerpt

Diviologen molecules of the general formula CH3(CH2)11V2+(CH2)6V2+(CH2)11CH3 (C12VC6VCI2, V2+ = 4,4'-bipyridinium or viologen) were employed to electrochemically assay DNA hybridization to PNA probes immobilized at Au electrodes. Immobilized 15-mer PNA probes were exposed to 25-mer DNA oligonucleotides containing either complementary or single base mismatched sequences. In the presence of complementary PNA-DNA...
