The effectiveness of magnetic microparticles in isolation of DNA from Lactobacillus rhamnosus CCM 1825T and DNA from chicken erythrocytes were studied in diploma thesis. Magnetic HEMA based microparticles coated by carboxylic groups and hyperbranched styrene-divinylbenzene particles (IMC AS ČR, Prague, Czech Republic) were used for DNA isolation. Magnetic microparticles Dynabeads® DNA DIRECT™ Universal (Dynal, Norway) based on polystyrene and MPG® Uncoated (PureBiotech, USA) based on magnetic glass were used as a control. The dependence of amount of eluted DNA on concentration of DNA in the base solution and the dependence of amount of eluted DNA on concentration of magnetic microparticles were studied. The affinity of magnetic microparticles to RNA for various concentrations of RNA solution was studied, too. The ability of tested particles to isolate DNA from real samples was validated using milk product Actimel. The quality of isolated DNA of Lactobacillus genus was proved using genus specific PCR.
