This method is based on reversibly binding DNA to a magnetic solid surface/ bead/particles, which have been coated with a DNA binding antibody or a functional group that interacts specifically with DNA. After DNA binds, beads are separated from other contaminating cellular components, washed and finally the purified DNA is eluted using ethanol extraction. This method is rapid and can be automated. However, it can be more costly than other methodologies. Examples are Agencourt DNAdvance Kit (Beckman Coulter), Magnetic Beads Genomic DNA Extraction Kit (Geneaid).
