Abstract

This protocol will allow users to operate the DNeasy® PowerSoil® Pro Kit.

Before start

Ensure that the PowerBead Pro Tubes rotate freely in the centrifuge without rubbing. * If Solution CD3 has precipitated, heat at 60°C until the precipitate dissolves.

  • Perform all centrifugation steps at room temperature (15–25°C).

Steps

Using the DNeasy® PowerSoil® Pro Kit

1.

Spin the PowerBead Pro Tube briefly to ensure that the beads have settled at the bottom. Add up to 250mg of soil and 800µL of Solution CD1. Vortex briefly to mix.

2.

Secure the PowerBead Pro Tube horizontally on a Vortex Adapter for 1.5–2 ml tubes (cat. no. 13000-V1-24). Vortex at maximum speed for 0h 10m 0s

Note
If using the Vortex Adapter for more than 12 preps simultaneously, increase the vortexing time by 5-10 minFor more information about other bead beating methods, see the “Protocol: Detailed” section of DNeasy® PowerSoil® Pro Kit Handbook.

3.

Centrifuge the PowerBead Pro Tube at 15000x g,0h 0m 0s for 0h 1m 0s

4.

Transfer the supernatant to a clean 2 ml Microcentrifuge Tube (provided)

Note
Expect 500–600 µl. The supernatant may still contain some soil particles

5.

Add 200µL of Solution CD2 and vortex for 0h 0m 5s

6.

Centrifuge at 15000x g,0h 0m 0s for 0h 1m 0s at Room temperature . Avoiding the pellet, transfer up to 700µL of supernatant to a clean 2 ml Microcentrifuge Tube (provided)

Note
Expect 500–600 µl.

7.

Add 600µL of Solution CD3 and vortex for 0h 0m 5s .

8.

Load 650µL of the lysate onto an MB Spin Column and centrifuge at 15000x g,0h 0m 0s for 0h 1m 0s

9.

Discard the flow-through and repeat step 8 to ensure that all of the lysate has passed through the MB Spin Column.

10.
  1. Carefully place the MB Spin Column into a clean 2 ml Collection Tube (provided).

Safety information
Avoid splashing any flow-through onto the MB Spin Column

11.

Add 500µL of Solution EA to the MB Spin Column. Centrifuge at 15000x g,0h 0m 0s for 0h 1m 0s

12.

. Discard the flow-through and place the MB Spin Column back into the same 2 ml Collection Tube.

13.

Add 500µL of Solution C5 to the MB Spin Column. Centrifuge at 15000x g,0h 0m 0s for 0h 1m 0s

14.

Discard the flow-through and place the MB Spin Column into a new 2 ml Collection Tube (provided).

15.

Centrifuge at up to 16000x g,0h 0m 0s for 0h 2m 0s . Carefully place the MB Spin Column into a new 1.5 ml Elution Tube (provided)

16.

. Add 50mL -100mL of Solution C6 to the center of the white filter membrane.

17.

Centrifuge at 15000x g,0h 0m 0s for 0h 1m 0s . Discard the MB Spin Column. The DNA is now ready for downstream applications

Note
We recommend storing the DNA frozen (–30 to –15°C or –90 to –65°C) as Solution C6 does not contain EDTA. To concentrate DNA, please refer to the Troubleshooting Guide.
