HighPrep^™ PCR Clean Up Kit and Purification System Protocol

PCR clean up beads and kit for post-PCR and NGS library construction

The HighPrep^™ PCR Purification System uses magnetic beads-based chemistry without centrifugation or filtration in a simple 3-step procedure that includes a bind, wash, and elution step. After HighPrep^™ PCR is added to the PCR reaction sample, the protocol utilizes a magnet plate (magnet stand) for processing the PCR reaction sample. During the process, contaminants and salts are washed off and pure DNA is eluted and ready to be used in subsequent applications.

HighPrep^™ PCR Protocol Materials

Number of reactions is based on typical 10µL PCR reaction volume. Volume of HighPrep^™ PCR reagent per reaction = 1.8 x (PCR Reaction Volume)

HighPrep^™ PCR 96-Well Protocol

Be sure to bring the HighPrep^™ PCR reagent to room temperature for at least 30 min before use.

1. Shake the HighPrep^™ PCR reagent thoroughly to fully resuspend the magnetic beads.
2. Transfer PCR reaction to appropriate 96-well plate.
3. For 50µl reaction, adjust volume using sterile water.

PCR Reaction Volume (µL)	HighPrep™ PCR Volume at 1.8X

20	36
50	90

Formula used to calculate the volume of HighPrep^™ PCR reagent needed for PCR reaction: HighPrep^™ PCR reagent volume per reaction = 1.8 X PCR reaction volume.

4. Add HighPrep^™ PCR reagent volume according to the PCR reaction.
5. See table below to determine appropriate volume.
6. Mix the HighPrep^™ PCR reagent and PCR sample thoroughly by mix pipetting up and down 6-8 times.
7. Incubate the mixture for 5 minutes at room temperature.
8. Place the sample plate on the 96 magnetic separation device for 3 minutes or until the solution clears. Beads will pull to the side of the well.
9. With the sample plate still on the magnet, remove and discard the supernatant by pipetting.

IMPORTANT: Do not disturb the attracted beads while aspirating the supernatant.

10. With the sample plate on the magnet, add 200 µl of 80% ethanol to each well and incubate for 30 seconds at room temperature.
11. With the plate still on the magnet, remove and discard the supernatant by pipetting.
12. Repeat steps 8-9 for a total of two 80% ethanol washes.
13. Dry the beads by incubating the plate for 10-15 minutes at room temperature with the plate still on the magnetic separation device.

IMPORTANT: It is critical to completely remove all traces of alcohol but take caution in not over drying the beads as this will reduce the yield.

14. Remove the sample plate from the magnetic separation device. Add 40µl of elution buffer (reagent grade water, TRIS-HCl pH 8.0 or TE buffer) to each well and pipet up and down 5 times to mix. Prewarming the elution buffer at 55°C can increase the yield.
15. Incubate for 2 minutes at room temperature.
16. Place the sample plate back on the magnetic separation device and wait 3 minute or until the magnetic beads clear from solution.
17. Transfer the eluate (cleared supernatant) to a new plate for storage or for subsequent applications.

HighPrep^™ PCR 384-Well Protocol

1. Shake the HighPrep™ PCR reagent thoroughly to fully resuspend the magnetic beads.
2. Transfer PCR reaction to appropriate 384-well plate. For 50µl reaction, adjust volume using sterile water.
3. Add HighPrep™ PCR reagent volume according to the PCR reaction
