Abstract
A series of protocols are proposed to extract genomic DNA from whole blood at different scales using carboxyl-functionalized magnetic nanoparticles as solid-phase absorbents. The enrichment of leucocytes and the adsorption of genomic DNA can be achieved with the same carboxyl-functionalized magnetic nanoparticles. The DNA bound to the bead surfaces can be used directly as PCR templates. By coupling cell separation and DNA purification, the whole operation can be accomplished in a few minutes. Our simplified protocols proved to be rapid, low cost, and biologically and chemically non-hazardous, and are therefore promising for microfabrication of a DNA-preparation chip and routine laboratory use.
