CDC researchers have developed a novel method that generates globally amplified DNA copies retaining parental methylation information; making accurate DNA-archiving for methylation studies much more feasible and cost-effective than undertaking such an endeavor with alternate technologies. This unique approach eliminates a significant bottleneck in the collection of methylation information in the genome(s) of an individual organism, hosts and pathogens. Thus, this technology provides numerous opportunities for investigations into cytosine methylation patterns, ultimately benefiting efforts of early detection, control and prevention of many chronic and infectious diseases.
