title: Application of magnetite and silica-magnetite composites to the isolation of genomic DNA.
abstract: Magnetite and silica-magnetite composites were used as adsorbents for the isolation of genomic DNA from maize kernels. Two methods are described for the preparation of silica-magnetite composites, both of which afford higher yields of genomic DNA than when using magnetite alone, or a commerically available kit. DNA isolated using silica-magnetite was suitable for use in further applications such as polymerase chain reaction amplification and enzyme digestion.
