Avoiding Cross-Contamination When Using the Harris Uni-Core Punch Tool in Thermo Scientific Direct PCR Protocols

Our Direct PCR approach saves time and cost by allowing amplification of DNA directly from various source materials. With starting materials such as plant leaves, mouse ears or filter papers, the easiest way to produce samples of small and uniform size is to use the Harris Uni-Core Punch Tool and Harris Cutting Mat Technology. We found that 2% sodium hypochlorite efficiently prevents cross-contamination of the samples from the tools.
