Abstract
In our study we compared the two widely used, commercially available and automation suitable magnetic bead-based extraction methods “iPrep Forensic Kit” and “PrepFiler Express BTA⢠Kit” to conventional organic solvent extraction. The results demonstrate that DNA extraction from standardized saliva samples applied to SceneSafe Fast⢠minitapes is most efficient with phenol-chloroform. We also provide evidence that SceneSafe Fast⢠minitapes perform better than wet cotton swabs in the sampling of touch DNA from cotton fabric. Applying the tape only once in every spot on the tissue is thereby sufficient for a considerably better collection performance of the tapes compared to swabbing.
