A microtiter plate-based high-throughput DNA purification method

A fast, reliable, inexpensive, and high-throughput method to purify DNA has been developed. It is based on DNA amplification by polymerase chain reaction utilizing a mini spin-column made from a 96-well membrane-bottomed assay plate. With this method, 50% of the DNA is recovered routinely using Sephacryl-500HR as filtration media. Purified DNA can then be used in various enzymatic manipulations, such as sequencing and hybridization. This provides an economical alternative protocol for routine large-scale purification of DNA templates for sequencing or other enzymatic manipulations.
