Product Infomation

Product Name	OH-SiO₂ Magnetic Beads, 1 μm
Catalog Number	MGB-BM-004
Size	1 mL, 10 mL, 100 mL
Physical Specs	1-4 μm
Description	Hydroxyl-modified silica magnetic beads are exclusively designed for nucleic acid extraction and purification. Their surface is functionalized with a large quantity of silanol (hydroxyl) groups, which can specifically bind to nucleic acids in solution through hydrophobic, hydrogen-bonding, and electrostatic interactions under high-salt and low-pH conditions, without binding to other impurities (e.g., proteins). They can quickly isolate nucleic acids from biological samples, featuring safe and simple operation that is highly beneficial for automated and high-throughput nucleic acid extraction.
Applications	Purification of PCR products; plasmid extraction; viral nucleic acid extraction; genomic DNA extraction from samples such as blood, tissue, plants, and microorganisms.
Features	Strong nucleic acid binding capacity, >20 μg DNA/mg magnetic bead; excellent operational performance, with uniformly dispersed magnetic beads exhibiting superparamagnetism and a magnetic response time <30 s; complete silica coating ensures stable performance.
Particle Size	1-4 μm
Concentration	50 mg/mL
Shell	SiO2
Form	Amorphous
