NGS Clean-Up Magnetic Bead Systems
Introduction

Magnetic bead-based clean-up systems are widely used in post-reaction nucleic acid workflows, particularly for PCR product purification, fragment size selection and sequencing reaction clean-up. These processes help remove residual primers, enzymes, salts and other reaction components prior to downstream analysis.

Within the Magen portfolio, clean-up bead systems are developed based on PEG-mediated binding chemistry, enabling selective adsorption of nucleic acids under controlled conditions. Depending on bead configuration and workflow parameters, these systems support routine DNA/RNA purification as well as more specialized applications such as fragment size control in NGS library preparation.

Different bead configurations are optimized for distinct workflow stages, including routine clean-up, selective removal of short fragments, RNA purification and sequencing reaction purification. This allows laboratories to build flexible and reproducible workflows across molecular biology and sequencing applications while maintaining compatibility with both manual handling and automated platforms.

DNA/RNA Binding Magnetic Bead Systems
Introduction

Magnetic bead materials provide a flexible platform for nucleic acid purification across a wide range of laboratory workflows, particularly where scalability, automation compatibility and adjustable binding conditions are required.

Within the Magen sample preparation portfolio, magnetic beads are engineered with defined surface chemistries, particle size distributions and magnetic response profiles to support DNA and RNA binding under chaotropic or PEG-mediated conditions. Silica-based particles are commonly used for nucleic acid extraction from routine, low-input or fragmented samples, while carboxyl-coated beads are applied in clean-up, size selection and enzymatic workflows such as NGS library preparation.

Different bead types are optimized for specific processing conditions, including sample input volume, nucleic acid abundance and fragment characteristics. This enables laboratories to select appropriate materials for applications ranging from general DNA/RNA isolation to circulating DNA workflows and post-extraction processing.

All magnetic bead systems are compatible with both manual protocols and automated platforms, supporting consistent performance across diverse laboratory environments.
