Product Infomation
Product Name OH-SiO₂ Magnetic Beads, 300-500 nm
Catalog Number MGB-BM-005
Size 1 mL, 5 mL, 10 mL, 50 mL, 100 mL
Physical Specs 300-500 nm
Description Silica magnetic beads with hydroxyl modification are specifically engineered for the extraction and purification of nucleic acids. Abundant silanol (hydroxyl) groups are modified on their surface, allowing them to specifically combine with nucleic acids in solution via hydrophobic interactions, hydrogen bonding, and electrostatic interactions under high-salt and low-pH conditions, while not interacting with other impurities such as proteins. They enable rapid separation of nucleic acids from biological samples with safe and easy operation, which is very favorable for automated and high-throughput nucleic acid extraction.
Applications PCR product purification; 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: uniformly dispersed magnetic beads with 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 stable performance.
