Analysis of DNA and single-base mutations using magnetic particles for purification, amplification and DNAzyme detection
Abstract
The amplified detection of DNA or of single-base mismatches in DNA is achieved by the use of nucleic acid-functionalized magnetic particles that separate the recognition duplexes and, upon amplification, yield chemiluminescence-generating DNAzymes as reporter units. The analysis of M13 phage ssDNA is achieved by the hybridization of the analyte to capture nucleic acid-functionalized magnetic particles followed by the binding of a DNA machine unit to the analyte domain.
