PureSil-Silica Magnetic Beads are Fe3O4 magnetic beads coated with a silicon dioxide (SiO2) layer. Since silica is able to bind to the nucleic acids, PureSil-Silica Magnetic Beads serve as a simple and efficient tool for plasmid DNA purification for transfection or sequencing applications, genomic DNA purification for research or clinical applications, RNA purification for qPCR analysis, or PCR product clean-up for downstream analysis.
