The BcMag™ One-Step PCR Cleanup Kit is a remarkable product that improves DNA purification procedures. This innovative kit enables ultrafast and highly efficient purification of post PCR or other DNA reactions, which reduces processing time and enhances research efficiency. Its simple protocol, which uses only one tube and one step, is a breakthrough in DNA purification. The protocol is highly flexible, and different size DNA fragments can be effortlessly removed by adjusting processing time, buffer’s pH, and detergent concentration.
With the BcMag™ One-Step PCR Cleanup Kit, purified DNA is ready for downstream applications in just one minute, significantly improving research efficiency. The purified DNA can be used in a wide range of downstream applications, such as Sanger Sequencing, Restriction Digestion, Cloning, SNP Detection, or Library Preparation for NGS. The kit’s unique Beads enable 96 samples to be processed simultaneously, and the entire process takes less than 10 minutes, making it the ideal solution for time-sensitive research.

B. Procedure
! Important !
1.
The following protocol is optimized for the efficient cleanup of 10μl DNA sample. The procedure may need to be optimized if an alternative reaction scale is used.
2.
Shake or vortex the bottle to completely resuspend the magnetic beads before using.
3.
Do not allow the magnetic beads to sit for more than two minutes before dispensing.
4.
Based on applications, the user should choose buffer conditions based on table 1. For example, if the sample does not contain detergent, add 1 μL of 1% Triton™ X-100 solution to a 10 μL sample (final concentration is 0.1%).

The assay was done by using the following conditions:
1. 10 mM Tris-HCl with or without 0.1% triton (final concentration) and three different: pH 7.5, pH 8.0 and pH 8.8
1.
Add 5 μL magnetic beads to the 10 μL DNA sample.
2.
If necessary, briefly centrifuge at 2500 rpm for 30 seconds to bring all contents to the bottom of the tube.
3.
Mix thoroughly for 1 minute by slowly pipetting up and down 25 times (one minute) or by vortex mixer for 5 minutes at 2500 rpm.
4.
If necessary, briefly centrifuge at 2500 rpm for 30 seconds to bring all contents to the bottom of the tube.
5.
Place the sample plate on the magnetic separation plate for 30 seconds or until the solution is clear to separate beads from the solution.
6.
Transfer the supernatant to a clean plate while the sample plate remains on the magnetic separation plate for downstream applications.
C. Troubleshooting
Problem
Low DNA Recovery
Probable Cause
Vertexing speed is too fast.
Vertexing time is too long.
Suggestion
Problem
Low DNA Recovery
Probable Cause
Using too many magnetic beads
Suggestion
Thoroughly resuspend the magnetic beads and use the correct amounts of the beads.
Problem
Failure to Remove Impurities.
Probable Cause
Used inappropriate PCR tubes or PCR plates
Suggestion
Make sure that the well diameter at the bottom of the conical section of PCR Tubes or PCR plates is ≥2.5mm.
Problem
Failure to Remove Impurities.
Probable Cause
Vortex speed is too slow, or vortex time is too short.
Suggestion

Failure to Remove Impurities.
Probable Cause
Using fewer magnetic beads
Suggestion
Thoroughly resuspend the magnetic beads and use the correct amounts of the beads.
Problem
Failure to Remove Impurities.
Probable Cause
Strong secondary structure of DNA fragments ( < 50bp dsDNA or < 100 mer ssDNA)
Suggestion
Denature the sample by heating it at 95°C for 2 min.
Problem
Failure to Remove Impurities.
Probable Cause
Too much primer, dimer, adaptor, free dye, and detergent
