OVERVIEW

The foodproof® Magnetic Preparation Kit III is designed for the rapid and safe high-throughput extraction of DNA from up to 200 mg sample material and food products from plant and animal origin. The kit uses Proteinase K for the lysis, and magnetic beads for the washing and purification steps, resulting in a high yield of highly purified DNA. After preparing and loading the plates into the foodproof RoboPrep® 32 or the KingFisher™ Flex instrument, all remaining purification steps are performed automatically without the need for external centrifugation steps. Each component of the kit has been tested against predetermined specifications to ensure consistent product quality.

General Information

Number of Reactions
The kit is designed for 480 reactions.

Storage Conditions

All buffers and kit components of the foodproof Magnetic Preparation Kit III should be stored at 15 to 25 °C and are stable for at least 12 months under these conditions.

Proteinase K: Lyophilized Proteinase K should be stored at 15 to 25 °C. Reconstituted Proteinase K must be stored at -20 °C. Avoid multiple freeze- thaw cycles of diluted Proteinase K.

Magnetic Beads: The magnetic particles should be stored at 15 to 25 °C.

Wash and Binding Buffers: Buffers charged with 2-propanol should be stored at room temperature and must be sealed accordingly. If any precipitates are visible within the provided solutions, dissolve them by carefully heating up to 30 °C.

Test Principle

The foodproof Magnetic Preparation Kit III in combination with the foodproof RoboPrep 32 or the KingFisher Flex instrument provides fully automated purification of total genomic DNA from up to 200 mg of raw material and food products of plant and animal origin. In combination with additional Lysis Buffer and Proteinase K, a protocol for up to 2 g of sample material is available (contact us for information). The DNA isolation process is based on patented magnetic bead technology, which relies on the interaction of nucleic acids with coated magnetic particles under suitable buffer conditions. The kit provides high quality DNA, which can be used directly in PCR applications.

The foodproof RoboPrep 32 and the KingFisher Flex instrument perform all steps of the DNA purification procedure automatically. The procedure requires only minimal user interaction, namely the initial loading of the system and the preparation of the sample material. Sample cross-contamination and reagent crossover is effectively eliminated by the provided purification assay.

Both instruments use magnetic rods to transport the DNA, bound to magnetic particles, through the various purification phases: binding, washing and elution. The volume of buffers and other liquids necessary for DNA isolation is reduced to a minimum. Eliminating the direct liquid handling and increasing the automation level results in a fast, reliable and robust technique.

To achieve effective lysis and high DNA yields, the samples are first lysed with optimized lysis buffer and Proteinase K in a separate step. After lysis, the DNA binds to the magnetic beads whereas contaminants, metabolites and enzyme inhibitors are efficiently removed during the following three wash steps. Finally, highly purified DNA is eluted in elution buffer.
The purified, high-quality DNA is ready for use in downstream applications such as PCR or can be stored at -20 °C for later use.

Workflows

The following procedures describe the automated DNA extraction from plant and animal species with the foodproof Magnetic Preparation Kit III in combination with our two extraction devices:

The foodproof RoboPrep 32 for low to medium throughput (32 samples per run) and the KingFisher Flex instrument for medium to high throughput (96 samples per run).

After preparing and loading the plates into the devices, no further manual steps are necessary. A complete run takes approximately 35 minutes.

Extraction Procedure A: RoboPrep® 32

This protocol describes semi-automated DNA extraction from 200 mg sample using the foodproof RoboPrep 32.
It consists of two parts: The manual preparation of samples and plates and the automated extraction run.
Please ensure that you have prepared all required reagents (see 2.2 Precautions and Preparations).
For a 16-sample run you will need the following consumables: 1 deep-well plate, 2 tip combs.
The RoboPrep® 32 processes two deep-well plates simultaneously (for a total of 32 samples).

  1. ADD SAMPLE
    Transfer up to 200 mg homogenized sample material into a 2 mL reaction tube and add 1,400 μL of Lysis Buffer and 70 μL of Proteinase K.

  2. INCUBATE
    30 min at 65 °C with shaking in the heating unit.

  3. CENTRIFUGE
    10 min at 12,000 x g.

  4. MARK PLATE ROWS
    Label the rows of the deep-well plate for the individual buffers to prevent pipetting errors when preparing the deep-well plate.
    Note: As a naming system, you can use the following abbreviations for buffers:
    B: Binding Buffer, WI: Wash Buffer I, WII: Wash Buffer II, 0: No buffer, E: Elution Buffer.

  5. ADD BUFFER TO RESPECTIVE ROWS
    Row 1 (and 7): add 250 μL Binding Buffer and 8 μL Magnetic Beads per well.
    Row 2 (and 8): add 600 μL Wash Buffer I per well.
    Row 3 (and 9): add 600 μL Wash Buffer I per well.
    Row 4 (and 10): add 800 μL Wash Buffer II per well.
    Row 5 (and 11): remains empty.
    Row 6 (and 12): add 200 μL Elution Buffer per well.
    Note: Before pipetting, take care that the magnetic beads are homogenously distributed.
    We recommend using multichannel pipettes to speed up liquid handling.

  6. ADD SAMPLES TO DEEP-WELL PLATE
    Transfer 500 μL lysate to row 1 (and 7) of the deep-well plate.
    Note: Avoid cross-contamination by NOT pipetting up and down during this step.

  7. SELECT PROGRAM
    Start the foodproof RoboPrep 32 instrument.
    Select the pre-installed program ‘MPK III’ via touchscreen.

  8. INSTALL TIP COMBS
    Open the front door.
    Insert tip combs.
    Note: Number of tip comps (tc) depends on number of samples that are processed:
    samples ≤ 8: 1 tc; samples 9-16: 2 tc; samples 17-24: 3 tc; samples 25-32: 4 tc.

  9. INSERT PLATE(S) AND START RUN
    To enter the deep-well plate, lower the heating block by pushing the lever backwards (1), slide in the plate (2) and push the lever in the opposite direction to raise the heating block and to lock the plate in place (3).
    Start the run. All the extraction steps will run automatically.
    Note: Details about the automated extraction steps and programming of the instrument can be found in the appendix.

READY FOR DETECTION

Rows 6 (and 12) of the plate contain the extracted DNA from the samples.
RECOMMENDATION: Use eluted DNA right after extraction. Additionally, it is recommended to analyze a 1:4 dilution, because the eluate may still contain PCR-inhibiting substances.

For later analysis, transfer extracts to tubes and store at -15 to -25 °C. For long-term storage, keep at -80 °C. After thawing, mix briefly by vortexing and centrifuge at high speed for 1 min.

Note: If the elution plate still visibly contains magnetic beads, you may centrifuge it to avoid interference with the detection kit (1 min at high speed).
The DNA is in the supernatant.

Extraction Procedure B: KingFisher Flex

This protocol describes the automated DNA extraction from up to 200 mg sample using the KingFisher Flex instrument. It consists of two parts: The manual preparation of samples and plates and the automated extraction run.

Please make sure that you have prepared all required reagents (see 2.2 Precautions and Preparations).
For a 96-sample run you will need the following consumables:
4 deep-well plates, 2 elution plates, 1 tip comb.
