Abstract: As part of the normal procedure in a forensic DNA laboratory, a quality control step of the
amplified DNA is often implemented to ensure the correct amplification of the sample before it is
analysed in downstream applications. A validation study was undertaken to investigate a new
microchip electrophoresis system (MultiNa, Shimadzu Corporation) claiming high resolution and
sensitivity compared to routine polyacrylamide gel electrophoresis (PAGE). An array of STR
multiplexes (AmpFISTR™ SGM+, GenePrint® FFFL, PowerPlex™ 16, PowerPlex™ Y, an in-house Y-STR
multiplex and AmpFISTR™ Profiler) were tested under both standard and low copy number PCR
parameters to evaluate the accuracy, reproducibility and sensitivity of this technique. These tests
showed that the microchip system did not have improved sensitivity compared to PAGE though had
increased resolution and high reproducibility between samples.
