Label-free sequence-specific DNA sensing using copper-enhanced anodic stripping of purine bases at boron-doped diamond electrodes

Stripping voltammetric determination of purine bases in the presence of copper ions at mercury, amalgam, or carbon-based electrodes has recently been utilized in analysis of DNA or synthetic oligodeoxynucleotides (ODNs). Here we report on co...

Determination of picogram quantities of oligodeoxynucleotides by stripping voltammetry at mercury modified graphite electrode surfacesAAA

The indirect analysis of the oligodeoxynucleotides (ODNs) is based on the electrochemical accumulation of the purine base residue-Cu(I) complex (hODN-Cu(I) complex) at the graphite electrode surface modified by a mercury layer. Finally follo...

Antisense Oligodeoxynucleotide-Mediated Gene Knockdown in Pollen Tubes

Specific gene knockdown mediated by the antisense oligodeoxynucleotides (AODNs) strategy recently emerged as a rapid and effective tool for probing gene role in plant cells, particularly tip-growing pollen tubes. Here, we describe the protoc...

Detection of abasic sites in DNA by electrochemical, immunoelectrochemical and acoustic methods using OsO4, 2,2,-bipyridine as a probe for unpaired thymine residues

Electrochemical, immunoelectrochemical and acoustic methods were applied in detection of DNA damage, in our case modeled by presence of abasic sites in short oligodeoxynucleotides of known sequence. Using complex of osmium tetroxide...
