Magnetic Silica Microspheres
For nucleic acids purification, a number of scientists have already replaced the centrifugation and organic extraction steps with our Magnetic Silica Particles (MSP). The silica magnetic beads are positively charged and therefore easily bind the negatively charged nucleic acids.This system enables laboratories to automatically process tens of thousands of samples per day.
Physical properties of MSP Silica Particles
• Diameter: ~ 1 µm
• Composition: > 95% magnetite
• Surface area: 16 - 22 m2 per mg (non porous)
• Binding capacity: > 10 µg DNA or RNA per mg
Presentation
• Particle content: 5 % (50 mg/ml).
• Pack sizes: 1 ml, 5 ml and 10 ml. Large volume are available on simple request.
• Buffer: our particles are suspended in water.
• Storage: our products must be stored at 4-8°C.
Exclusive features of MSP Silica Particles
• Adsorb leucocytes from whole blood
• Adsorb bacteria from growth medium
• Adsorb viruses from plasma
• Bind nucleic acids under chaotropic and under acidic conditions
• Allow washing buffers without ethanol
Applications of MSP Silica Particles
• Adsorption of bacteria
• Adsorption of viruses
• Adsorption of leucocytes
• Isolation of genomic DNA from blood
• Isolation of genomic DNA from bacteria
• Isolation of viral DNA/RNA
• Purification of PCR fragments
• Dye removal from sequencing reactions
• Isolation of plasmid DNA
