The Monarch Spin PCR & DNA Cleanup Kit (5 μg), a newer version of our original PCR cleanup kit, offers an efficient method for purification and concentration of up to 5 μg of high-quality, double-stranded and single-stranded DNA from enzymatic reactions such as PCR, restriction digestion, ligation, and reverse transcription. This new version features upgraded spin columns precision-engineered to uniquely allow for low elution, in as little as 5 μl, for highly concentrated DNA in downstream applications such as sequencing, restriction digestion, library construction, labeling and other enzymatic manipulations. Our optimized buffer system allows efficient binding and purification of the DNA, without a need to monitor pH. These kits contain uniquely designed columns and bottles to significantly reduce plastic usage compared to leading suppliers, while maintaining structural integrity for centrifugation, vacuum manifolds and other steps.
