EZ-10 Spin Column Plasmid DNA Miniprep Kit, Low Copy Plasmid: The EZ-10 Spin Column Kits provide a simple and efficient method for purification of plasmid DNA, extraction of DNA from agarose gels, and purification of DNA from enzymatic reactions such as PCR or restriction enzyme digestions. The DNA is selectively adsorbed in silica gel-based EZ-10 column and other components are washed away. The DNA is then eluted off the column and can be used for any downstream applications. The purification method used in these protocols does not require use of phenol, chloroform, or CsCl. The DNA is purified without an additional step of ethanol precipitation.
