The application of magnetic particles for DNA isolation from selected vegetable products

Micromethod of DNA isolation using magnetic particles is one of the modern technological methods used in DNA isolation, and makes the process simpler, more effective and faster. The main aim of this study was to isolate the DNA from various plant (tomato) food products, using different types of magnetic particles. The results were compared and the quantity, purity and the possibility of amplication of the isolated DNA among samples were found to be different. The DNA isolation method using magnetic particles P(HEMA-co-GMA) or HPS B-M-NH2 was shown to be the most effective in achieving the above mentiond parametres. DNAs from the analysed samples of plant food products were isolated in sufficient quantity and quality to be used in the conventional PCR. Differences in the possibility of the amplification of the isolated DNA stored at -20 °C during more than a half year were not found
