Silica Hydroxyl Magnetic Beads (500 nm) designed for nucleic acid extraction and purification, this product features superparamagnetic Fe₃O₄ as the core and a surface rich in hydroxyl-functionalized silica (–SiOH) groups. It exhibits high magnetic content and excellent monodispersity. Under specific conditions, nucleic acids can specifically bind to the hydroxyl groups on the bead surface, enabling rapid and accurate nucleic acid isolation from complex samples.
Product Features
1.Fast magnetic response and excellent monodispersity ; bead size distribution: CV < 5%.
2.Low batch-to-batch variation and high reproducibility.
3.Good biocompatibility and low cytotoxicity.
Applications
The product is broadly applicable to various immunoassays and separation procedures, including:
1.Genomic DNA extraction from whole blood, tissues, plants, microorganisms, and other samples.
2.Viral DNA/RNA and total RNA extraction.
3.Purification of PCR products.
4.Plasmid DNA extraction.
Precautions
1.Thoroughly resuspend the beads before each use to avoid changes in bead concentration during sampling. Avoid prolonged sonication to prevent damage to the bead surface.
2.After removal from the container and before use, perform magnetic separation and wash the beads 2–3 times with purified water or the desired buffer solution.
3.Avoid freeze‑thaw cycles or drying of the magnetic beads during use and storage.
