Electrochemical Detection of Global DNA Methylation Using Biologically Assembled Polymer Beads

Abstract: DNA methylation is a cell-type-specific epigenetic marker that is essential for transcriptional regulation, silencing of repetitive DNA and genomic imprinting. It is also responsible for the pathogenesis of many diseases, including cancers. Herein, we present a simple approach for quantifying global DNA methylation in ovarian cancer patient plasma samples based on a new class of biopolymer nanobeads. Our approach utilises the immune capture of target DNA and electrochemical quantification of global DNA methyla… Show more

“…Recently, we designed a versatile technology platform based on bioengineered polymer nanobeads for efficient capture and electrochemical detection of DNA methylation in ovarian cancer patient samples. 227 Engineered polyhydroxybutyrate (PHB) nanobeads were utilized as electrode surface modifiers that facilitated the adsorption of 5 mC antibody (specific antibody for methylated DNA). This method could detect methylation changes as low as 5% in ovarian cancer cell lines and plasma DNA samples.…”

“…27,28 Although effective, the use of an NHC with a maleimide end group for immobilization of the TLR protein moiety through Michael addition reaction required the use of thiol nucleophiles that provided a point of potential instability due to reversible reactions. 27,29 Despite the current precedents, such as DNA hybridization, [30][31][32] nanobeads, 33 or a reverse method of using DNA platform to detect proteins, 34 there has not yet been a reported example of electrochemical biosensors using organic ligand SAM technology along with TLRs to detect DNA molecules.…”
