Abstract

In this study, we compare the performance of a simple PVP extraction method with a commercially available and widely used kit for recovering DNA from adhesive tapes. This novel method shows almost 60% higher DNA recovery from blood deposits on SceneSafe Fast™ minitapes when compared to the PrepFiler™ BTA Forensic DNA Extraction Kit. We also demonstrate how a simple modification of the magnetic bead-based purification step can lead to better recovery and removal of PCR inhibitors.
