yield and purity in order to detect even traces of gm components in subsequent PCR analyses. Furthermore, these methods must be effective and reproducible. In contrast to the PCR, which has often been automated [3], CTAB buffer-based DNA extraction methods, as a prerequisite for the PCR analysis, are still performed manually. This is due to the fact that automated DNA extraction methods and commercially available DNA extraction kits are incompatible with CTAB extraction buffers unless the CTAB is removed during the DNA extraction by application of chloroform and a subsequent DNA precipitation step. Hence, it was the aim of this work to develop and optimise an automated CTAB-compatible DNA extraction protocol for seed using the Maxwell 16 instrument (Promega GmbH, Mannheim, Germany) and to compare this method to commonly used manual DNA extraction methods. The Maxwell 16 extraction robot has already been applied for different kinds of matrices like blood or bacterial cells [8, 9], but so far, none of the available extraction kits is suitable for CTAB buffer-based DNA extraction from seed or from plant material in general.
