title: High-throughput DNA extraction from old paraffin-embedded biopsies.
abstract: We have developed a rapid and reliable microporous spin-column-based method for high-throughput extraction of DNA from old paraffin-embedded biopsies. The method was developed specifically for PCRs and molecular genetic studies. De-waxing and DNA extraction from tissues is performed in only one vessel, minimizing pipetting steps and eliminating supernatant/pellet procedures. All steps are performed at 60 degrees, 55 degrees and 95 degrees C minimize deleterious DNase activity. The amount of the extracted DNA was measured spectrophotometrically, and the quality of the extracted DNA and the PCR products was controlled on ethidium bromide-stained 3% agarose gel. The presented method for DNA extraction is less laborious and more convenient than previously published methods. It provides means by which extensive, paraffin-embedded material can be subjected to molecular genetic studies.
