Abstract

The development of a nucleic acid extraction method based on magnetic separation has opened up possibilities forl automation of DNA extraction. The BioRobot M48 is one of robotic stations applicable to automated DNA extraction in forensics. However, each new method should be thoroughly validated before application to routine casework. Our aim was to compare the effectiveness of the currently utilized organic/Microcon 100 based extraction procedure and magnetic extraction with BioRobot M48. The DNA concentration of DNA extracts obtained from different kinds of typical forensic material was evaluated followed by amplification with the SGM Plus or Identifiler kit and capillary electrophoresis using ABI 3100 Avant. We can conclude that BioRobot M48 is a very effective instrument for DNA extraction from most specimens and can be successfully applied in forensic laboratories.
