This application note provides an analysis of prepGEM as an efficient DNA extraction method for mice and rats, shown to produce high-quality DNA for hundreds of samples in under an hour. In this comparative study, prepGEM yielded readily-amplified DNA with no migration distortion or smearing. Yield from the prepGEM approach was significantly higher than the other two commercially available kits (100.0 ng/mg of tissue from 2 mm tail tips for prepGEM vs 6.43 ng/mg and 1.83 ng/mg of tissue from 5 mm tail tips. prepGEM’s high performance is attributed to the high-temperature proteinase that releases DNA without chemical denaturants that can carry over into downstream reactions and cause reduced performance.
