A novel DNA purification technology is described that enables tile purifica
tion of pure dsDNA from blood When compared to existing DNA purification me
thods, the Whatman BioScience Purification System (WBPS) offers a fast and
convenient way to recover high yields of DNA. WBPS is based on a unique fil
ter system that entraps DNA within a matrix. This allows the process to be
performed in a single unidirectional reaction vessel, reducing user interac
tion and multiple centrifugation steps.
