Product Details

Using Inhibitor Removal Technology, the DNeasy PowerWater Kit isolates genomic DNA from filtered water samples, free from salts, metals, humic substances and other organic materials. The kit can isolate high-quality DNA even from water containing high levels of contaminants. Resulting DNA can be used in any downstream application, including qPCR, Sanger sequencing and next-generation sequencing. Viable DNA can be acquired from common filter membrane types, including 0.45 μm and 0.22 μm filter funnels. DNA is ready to use in a final 100 μl volume. Want to try this solution for the first time?

Are there important considerations for plasma generation and urine handling?

It is strongly advised to follow the recommendations for preparing sample material provided in the corresponding Protocol Sheet to ensure reliable results.

Plasma: It is recommended to perform plasma separation immediately after blood collection when using EDTA or citrate as anticoagulant to prevent the release of genomic DNA into the plasma fraction.

Urine: Because circulating cell-free DNA in non-stabilized urine samples is rapidly degraded after sample collection due to high nuclease activity, eluates may contain no DNA or exhibit low DNA concentration. Therefore, it is recommended to stabilize urine samples. Even when using stabilized urine, it is recommended to perform a centrifugation step immediately after stabilization to prevent the release of genomic DNA from cells. Alternatively, non-stabilized urine samples can be processed immediately after collection and centrifugation using ATL-pretreatment and automated DNA extraction as described in the corresponding Protocol Sheet.
