BioPioneer's plasmid DNA isolation kit provides a simple and efficient method for miniprep plasmid DNA. The plasmid DNA is selectively adsorbed in silica based membrane, and other impurities such as protein, salt, nucleotides are washed away. The eluted DNA can be used for downstrem application such as PCR, restriction enzyme digesion, DNA sequencing. The whole procdeure takes 15-20 minutes. No phenol/chroloform extraction and ethanol precipitation is required. High capacity, up to 20ug plasmid DNA can be isolated.
