Abstract

Cytosine methylation and frequency of non-methylated CpG dinucleotides are genomic properties varying greatly between mammals and bacteria. A new DNA enrichment technology uses the specific affinity of the CXXC zinc finger domain for non-methylated CpG dinucleotides for powerful bacterial nucleic acid separation and enrichment. Application of the technology in sample preparation allows a 50-fold enrichment of minute amounts of bacterial DNA relative to a high mammalian DNA background.
