Magnetic bead-based reagent SuperMag OH

microspherefor researchtissue

Product overview
SuperMag OH-500 nm magnetic microspheres (Catalog No.: SM-HMM-0003) are SiO2-shell particles with hydroxyl (-OH) surface groups engineered for efficient nucleic acid extraction and purification. Under high-salt/low-pH conditions they selectively bind nucleic acids and enable rapid magnetic separation compatible with automated and high-throughput workflows.

Key Properties / Features

• Binding capacity: >20 µg DNA per mg magnetic beads
• Average particle size: 300–500 nm (monodisperse)
• Superparamagnetic: magnetic response time <30 s
• Complete SiO2 coating and OH surface enabling standard conjugation chemistries (e.g., EDC/NHS, glutaraldehyde)
• Available concentrations: 10 mg/mL and 50 mg/mL

Applications

• PCR product purification
• Plasmid extraction
• Viral nucleic acid extraction
• Genomic DNA extraction from blood, tissue, plant and microbial samples

Storage & Shelf life
Store at 2–8°C; short-term storage or transport at room temperature acceptable. Preservation fluid: 20% ethanol. Shelf life: 2 years.
