NucleoMag DNA Food
The NucleoMag DNA Food kit is designed for the isolation of DNA from food and feed samples, preferably of plant or animal origin. The procedure is based on reversible adsorption of nucleic acids to paramagnetic beads under appropriate buffer conditions. Sample lysis is achieved by incubation of samples with Proteinase K at 65 °C. Lysis mixtures should be cleared by centrifugation or filtration in order to remove contaminants and residual cellular debris. For binding of nucleic acids to the paramagnetic beads, Binding Buffer CB and the NucleoMag B-Beads are added to the clear lysate. After magnetic separation, the paramagnetic beads are washed to remove contaminants and salts using Wash Buffers CMW, CQW, and 80 % ethanol. Residual ethanol from previous wash steps is removed by air drying. Next, highly purified DNA is eluted with low-salt Elution Buffer (CE) and can be used directly for downstream applications. The NucleoMag DNA Food kit can be used either manually, or automated on standard liquid handling instruments and automated magnetic separators.

Reliable DNA isolation from diverse food and feed samples
DNA was isolated from five different sample matrices (n=8 for each sample type), among them samples rich in polysaccharides and fats as well as highly processed materials. DNA was quantified photometrically. The isolation yielded high amounts of DNA from all samples materials tested (>10 µg DNA for all samples).
Reliable qPCR performance from diverse food and feed samples
DNA isolated from five different sample matrices (n=8 for each sample type) was used as input for a subsequent qPCR targeting a 103 bp actin amplicon.
