DNA Extraction from Agarose Gels Protocol DNA Extraction from Agarose Gels Protocol. The page includes cutting out the DNA band from the gel, and describes three methods including 1) Spin-columns (Nucleic acid purification columns), 2) using Dialysis tubing (semi-permeable membrane, Visking tubing), and the 3) Paper strip method.Matt Lewis, Department of Pathology, University of Liverpool.
DNA Fragment Purification from Agarose Protocol DNA Fragment Purification from Agarose Protocol. This protocol is best for fragments from 200 bp to 10 kb the agarose purification is ideal. For smaller fragments (20 bp to 400 bp) the acrylamide purification is preferred.
Rapid Elution of DNA Agarose Gels Protocol Rapid Elution of DNA Agarose Gels Protocol. This method allows quick purification of DNA fragments from agarose gels for use in cloning and other reactions. Higher yields of purified DNA can be obtained from commercially available purification kits, however greater ligation efficiencies per given amount of DNA have been seen with the use of these described spin columns.
