Genomic DNA purification

Product overview

The NucleoMag cfDNA kit is designed for the efficient isolation of circulating cell-free DNA (cfDNA) from human blood plasma. Fragmented DNA as small as 50 bp can be purified at high yield due to a reversible adsorption of nucleic acids to paramagnetic beads under specialized buffer conditions. The yield can vary depending on the sample and is typically in the range of 0.1 to 100 ng DNA per ml of plasma. The purification procedure takes less than an hour for 24 preps.

Sample lysis is achieved by incubation of plasma with Liquid Proteinase K and Lysis Buffer MCF1 at 56°C. Buffer MCF2 and paramagnetic NucleoMag P-Beads are then added, enabling optimal binding of nucleic acids. Three washing steps efficiently remove contaminating substances, such as PCR inhibitors, after magnetic separation. Residual ethanol is removed by a drying step, and highly pure DNA is eluted from the paramagnetic beads with 50–200 µl of Elution Buffer MCF5—a slightly alkaline buffer of low ionic strength (5 mM Tris/HCl, pH 8.5). The NucleoMag cfDNA kit can be used either manually or on automated liquid handling platforms or magnetic separators. Back Reliable purification of cfDNA from different volumes of plasma Reliable purification of cfDNA from different volumes of plasma. The NucleoMag cfDNA (formerly known as NucleoMag DNA Plasma) kit was used to isolate cfDNA from 2–10 ml inputs of EDTA-treated human plasma. Analysis of purified cfDNA on the Agilent Bioanalyzer 2100 system using the High Sensitivity DNA Kit yielded a characteristic peak at 170 bp for each input volume. The total yield from each sample was determined using the PicoGreen quantification assay with the Quant-iT PicoGreen kit on a Synergy HT Multi-Detection Microplate Reader (Biotek).

Total cfDNA was purified from 2-ml inputs of EDTA-treated human plasma from four challenging donor samples containing low levels of cfDNA (<10 ng cfDNA/ml of plasma) using NucleoMag cfDNA (formerly known as NucleoMag DNA Plasma) and a kit from Competitor T. Total DNA recovery was quantified using the Qubit dsDNA High Sensitivity kit on a Qubit fluorometer. Relative to the kit from Competitor T, NucleoMag cfDNA provided higher yields with lower sample-to-sample variability.
