High-throughput purification of DNA from soil: NucleoSpin 8/96 Soil
Soil samples contain different amounts of organic matter and inorganic material (humic substances or polysaccharides) and exhibit different pHs, all of which can hinder the consistency of DNA extraction from these sample types. The NucleoSpin 8/96 Soil kits overcome these obstacles through the use of highly optimized lysis conditions and mechanical disruption. Using these kits with 500 mg of soil as a starting material typically yields 2–10 µg of eluted genomic DNA that is ready to use for downstream applications such as PCR, qPCR, restriction analysis, etc.
Alternative lysis buffers and additional Enhancer SX enable optimization of the protocol to maximize yields from soil samples of different compositions
MN Bead Tubes Type A (ceramic beads) facilitate more efficient lysis of soil microorganisms and reduce risk of cross-contamination
NucleoSpin Inhibitor Removal Strips/Plate allow for elimination of all PCR inhibitors, such as humic substances
Centrifugation: Centrifuge-based processing of NucleoSpin 8/96 Soil kits requires a microtiter plate centrifuge which is able to accommodate the NucleoSpin Soil Strips/Plate stacked on a round- or square-well block or rack with tube strips. The centrifuge must be able to reach an acceleration of 5,600–6,000g (bucket height: 85 mm). Centrifuge-based processing of 8-well strips requires the reusable Starter Set C, which contains Column Holders C, NucleoSpin Dummy Strips, MN Square-well Blocks, and Tube Strips.
Vacuum processing: The NucleoSpin 8/96 Soil kits also allow for manual processing with the NucleoVac 96 Vacuum Manifold. Additionally, a suitable centrifuge for sample preparation steps may be required. Vacuum processing of 8-well strips and automation on laboratory platforms with standard 96-well plate vacuum chambers require the reusable Starter Set A, which contains Column Holders A and Dummy Strips.
