Application Note: Electrochemical probes

Thursday, 1 October 2020

Electrochemical probes are comprised of an oligonucleotide modified with a redox reporter on one terminus and an electrode surface at the other. Upon hybridization of a target to a redox reporter, a change in the electrochemical response of the reporter can be measured and used to detect the target. This format has been used for the detection of single-base mismatches, DNA methylation, important analytes, abasic sites, and DNA damage*.
