The increasing amount of gm crops grown worldwide, however, has lead to an increased labour input and costs. A large part of the labour input is caused by time-consuming manual DNA extraction procedures, like the CTAB bufferbased DNA extraction. Extraction buffers containing CTAB (cetyltrimethylammonium bromide) proofed to be most suitable for an optimal chemical pulping of plant cells and are therefore commonly used for DNA extraction from plant material [7, 11]. Suitable DNA extraction methods in gm crop analysis must be capable isolating DNA with high
