The application of magnetic particles for DNA isolation from cereal products
 Starenkova, Anastasiia ; Španová, Alena (referee) ; Rittich, Bohuslav (advisor)
The thesis has been focused on micro method for isolation of PCR- ready DNA iusing magnetic particles from cereal products. Cereal biscuits and cereal products for babies were selected for the analysis. These were homogenized using plastic copist in lysis buffer with cetyltrimethylammonium bromide (CTAB). The homogenates were purified using chloroform- octanol mixture. The effect of isopropanol in the preparation of homogenates was tested, too. Homogenates were used for DNA isolation by magnetic particles. Two ways to isolate magnetic particles with bounded DNA (magnetic separator and magnetic needle have been tested. Isolated DNA was analyzed spectrophotometrically its concentration and purity were assessed. . After that, amplification of the DNA was tested in PCR. Two sets of primers specific for plant ribosomal DNA were used for their amplification. PCR products of expected length 700 bp and 220 bp were detected by agarose gel electrophoresis. It was shown that DNA isolated from seeds and cereal products using magnetic particles was in PCR-ready quality.
