General Surface

Background: There are different methods for genomic DNA extraction. Magnetic nanoparticles (MNPs) exhibit many important features making them suitable for DNA extraction. Objectives: The aim of this study was to compare the effect of monolayer and bilayer MNPs on genomic DNA extraction. Materials and Methods: The genomic DNA was extracted from the Staphylococcus aureus strain ATCC 25923 and clinical isolates using monolayer MNPs SiO2 and Fe3O4 and bilayer MNPs SiO2/Fe3O4. Then, the quality and quantity of the obtained genomic DNA were compared with both NPs. Results: The obtained results showed the concentration and purity of the extracted genomic DNA using bilayer magnetic NPs was significantly higher in comparison to the extracted genomic DNA by monolayer MNPs. Conclusion: In general, surface-coated MNPs are much more efficient than naked MNPs for genomic DNA extraction.

Low Efficiency

Tobacco (Nicotiana tabacum) cv. ‘Bright Yellow 2’ (BY2) cell suspension is a useful system to study the structure and function of plant cell. However, low efficiency of Agrobacterium-mediated transformation, and transgene silencing during subculture limit its application. Here we present optimization of the traditional protocols of Agrobacterium-mediated transformation and genomic DNA extraction. The transforming efficiency and recovery ratio of genomic DNA extraction were substantially increased by these improvements. Southern assay demonstrated that copy number of transgene could be determined unambiguously. Meanwhile by monitoring the GFP fluorescence we found that the GFP expression can keep stable in suspension culture cells for at least 20 days in liquid medium. Finally, applicability of constitutive promoters of Arabidopsis thaliana UBIQUITIN10 (AtUBQ10) and ARABIDOPSISSKP1 HOMOLOGUE1 (AtASK1) also can drive stable GFP expression in vivo of BY2 cells like CaMV 35S promoter in this plant system./span>
