Abstrakt: The 1.2 mm Electric Coring Tool (e- Core™) was developed to increase the throughput of FTA sample collection cards used during forensic workflows and is similar to a 1.2 mm Harris manual micro-punch for sampling dried blood spots. Direct short tandem repeat ( STR) DNA profiling was used to compare samples taken by the e- Core tool with those taken by the manual micro-punch. The performance of the e- Core device was evaluated using a commercially available Power Plex™ 18 D STR System. In addition, an analysis was performed that investigated the potential carryover of DNA via the e- Core punch from one FTA disc to another. This contamination study was carried out using Applied Biosystems Ampfl STR™ Identifiler™ Direct PCR Amplification kits. The e- Core instrument does not contaminate FTA discs when a cleaning punch is used following excision of discs containing samples and generates STR profiles that are comparable to those generated by the manual micro-punch.
