Product Infomation

Product Name	OH-SiO₂ Magnetic Beads, 500 nm, 10 mg/mL
Catalog Number	MGB-BM-001
Size	5 mL
Physical Specs	500 nm
Description	Hydroxyl-modified silica magnetic beads are specifically designed for nucleic acid extraction and purification. With a large number of silanol (hydroxyl) groups modified on their surface, they can specifically bind to nucleic acids in solution through hydrophobic interactions, hydrogen bonding, and electrostatic interactions under high-salt and low-pH conditions, while not binding to other impurities (such as proteins). They can quickly separate nucleic acids from biological samples, with safe and simple operation, which is very conducive to the automated and high-throughput extraction of nucleic acids.
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 uniform bead dispersion, superparamagnetic properties, and a magnetic response time <30 s; good stability and batch-to-batch reproducibility, with a polydispersity index <0.2 and monodisperse distribution; fully coated with a silica layer for consistent performance.
Particle Size	500 nm
Concentration	10 mg/mL
