(A) Plasmid DNA concentrations and (B) A260/A280 and A260/A230 absorbance ratios were measured spectrometically. The average values ± standard deviations of n=23 replicate extractions are shown.

Magnetic bead-based extraction uses magnetic beads coated with nucleic acid binding agents, such as silica, oligo (dT), or carboxyl groups, to capture genomic DNA, RNA, plasmid DNA, and mitochondrial ...
