MAGneat PCR Clean Up Beads – Ampure XP Alternative

What are MAGneat PCR Clean Up Beads?
Answer: MAGneat PCR Clean Up Beads are SPRI-based magnetic bead reagents designed for post-PCR DNA purification and size-selective clean-up. They provide an alternative to AMPure XP for workflows requiring removal of primers, primer dimers, unincorporated dNTPs, salts and enzymes before downstream applications such as sequencing, cloning and library preparation.

Why should PCR products be cleaned up?
Answer: PCR clean-up removes residual reaction components that may interfere with downstream applications. Removing primers, primer dimers, unincorporated dNTPs, enzymes and salts helps produce purified PCR products or DNA fragments suitable for sequencing, cloning, library preparation and other DNA analysis workflows.

What contaminants do the beads remove?
Answer: MAGneat PCR Clean Up Beads are designed to remove unwanted PCR components, including primers, primer dimers, unincorporated dNTPs, salts, enzymes and other residual reaction components, leaving purified DNA ready for downstream applications.

How do magnetic PCR clean-up beads work?
Answer: MAGneat PCR Clean Up Beads use Solid Phase Reversible Immobilisation (SPRI) technology to selectively and reversibly bind DNA to magnetic beads under appropriate buffer conditions. A magnet is then used to separate the DNA-bound beads from the sample, allowing unwanted reaction components to be removed during wash steps before the purified DNA is eluted. The bead-to-sample ratio can be adjusted to influence which DNA fragment sizes are retained, enabling size-selective purification.

What DNA fragment sizes can be recovered?
Answer: MAGneat PCR Clean Up Beads are designed for efficient recovery of PCR products while removing smaller unwanted reaction components. DNA recovery is influenced by fragment size and the bead-to-sample ratio. Refer to the recommended protocol for application-specific bead ratios and fragment-size recovery.

Can the beads remove primer dimers?
Answer: Yes. MAGneat PCR Clean Up Beads are designed to remove primer dimers and other unwanted small reaction components, helping improve the quality of purified PCR products for downstream applications.

Can the beads remove unincorporated dNTPs?
Answer: Yes. The clean-up workflow removes unincorporated dNTPs, along with salts, enzymes and other residual PCR components that may interfere with downstream applications.

Are the beads suitable for Sanger sequencing?
Answer: Yes. Purified PCR products are suitable for Sanger sequencing following appropriate downstream sample preparation.

Can the purified DNA be used for Next Generation Sequencing (NGS)?
Answer: Yes. DNA purified using MAGneat PCR Clean Up Beads can be used in Next Generation Sequencing (NGS) and library preparation workflows where clean PCR products or DNA fragments are required.

Are the beads suitable for cloning applications?
Answer: Yes. Purified PCR products can be used in cloning workflows, including applications requiring removal of residual primers, dNTPs, enzymes and salts before downstream processing.

Can the beads be used for DNA fragment size selection?
Answer: Yes. MAGneat PCR Clean Up Beads can be used for DNA fragment size selection by adjusting the bead-to-sample ratio. Changing this ratio alters the size range of DNA fragments that bind to the magnetic beads, allowing smaller fragments to be excluded or selected depending on the workflow. Refer to the recommended protocol for application-specific bead ratios and fragment-size recovery.

Can PCR products generated with different DNA polymerases be cleaned up?
Answer: Yes. MAGneat PCR Clean Up Beads are suitable for purification of PCR products generated using a range of commonly used DNA polymerases and PCR mastermixes.

Can the workflow be automated?
Answer: Yes. The magnetic bead-based workflow is designed for both manual and automated processing and can be integrated into compatible magnetic bead purification platforms.

Which automation platforms are supported?
Answer: MAGneat PCR Clean Up Beads can be used with compatible automated magnetic bead processing systems, including the KingFisher® Purification System and the HeiDi-NA automated magnetic bead processing system. The HeiDi-NA processes up to 16 samples per run. For other automated platforms, contact Microzone for workflow-specific recommendations and support.

What equipment is required?
Answer: For manual purification, typical equipment includes a magnetic separation rack, air-displacement pipettes with appropriate filter tips, and compatible tubes or microplates. Automated processing can be performed using a compatible magnetic bead processing or liquid-handling platform.

Are any additional reagents required?
Answer: Additional reagents include freshly prepared 80% ethanol and an appropriate DNA elution buffer or molecular-grade water, depending on the workflow.

How long does the clean-up process take?
Answer: MAGneat PCR Clean Up Beads provide a rapid PCR purification workflow. Total processing time is around 15 minutes but may vary depending on sample number, format and whether purification is performed manually or using an automated platform.

How should the beads be stored?
Answer: Store MAGneat PCR Clean Up Beads according to the conditions specified in the product instructions. Ensure the beads are thoroughly resuspended before use and avoid freezing unless otherwise specified.

What downstream applications are supported?
Answer: Purified DNA is suitable for a range of downstream applications, including Sanger sequencing, Next Generation Sequencing (NGS), library preparation, cloning, genotyping and other molecular biology workflows requiring purified PCR products.

How do MAGneat PCR Clean Up Beads compare with spin-column purification?
Answer: MAGneat PCR Clean Up Beads use SPRI-based magnetic bead technology rather than spin columns, eliminating column-based centrifugation steps and providing an automation-friendly workflow. Magnetic beads also offer high DNA-binding capacity and minimise shear stress, supporting efficient DNA recovery while allowing the bead-to-sample ratio to be adjusted for size-selective purification.

Are MAGneat PCR Clean Up Beads an alternative to AMPure XP beads?
Answer: Yes. MAGneat PCR Clean Up Beads are a SPRI-based magnetic bead alternative to AMPure XP for post-PCR DNA purification and size-selective workflows. They use the same general principle of reversible DNA binding to magnetic beads and allow the bead-to-sample ratio to be adjusted for PCR clean-up and fragment size selection.

Why choose MAGneat PCR Clean Up Beads?
Answer: MAGneat PCR Clean Up Beads provide a simple, efficient and automation-friendly solution for post-PCR DNA purification. The SPRI-based magnetic bead workflow removes primers, primer dimers, unincorporated dNTPs, salts and enzymes while recovering purified DNA suitable for applications including Sanger sequencing, NGS, library preparation, cloning and genotyping. The adjustable bead-to-sample ratio also enables size-selective purification, making MAGneat PCR Clean Up Beads a flexible alternative to AMPure XP for both manual and automated workflows.
