Product Infomation

Product Name	OH-SiO₂ Magnetic Beads, 500 nm, 50 mg/mL
Catalog Number	MGB-BM-002
Size	1 mL, 5 mL, 20 mL, 100 mL, 1000 mL
Physical Specs	500 nm
Description	Hydroxyl-functionalized silica magnetic beads are specially developed for the extraction and purification of nucleic acids. Their surface is modified with abundant silanol (hydroxyl) groups, enabling them to specifically interact with nucleic acids in solution via hydrophobic, hydrogen-bonding, and electrostatic forces under high-salt and low-pH environments, without associating with impurities like proteins. These beads allow rapid isolation of nucleic acids from biological samples with safe and easy operation, making them highly suitable for automated and high-throughput nucleic acid extraction processes.
Applications	Purification of PCR products; plasmid extraction; viral nucleic acid extraction; genomic DNA extraction from samples such as blood, tissue, plants, and microorganisms.
Features	Superparamagnetism and high magnetic responsiveness save processing time. Excellent dispersion and resuspendability facilitate efficient nucleic acid binding and recovery. Good physicochemical stability ensures reproducible results.
