Silica Coated Magnetic Microparticles | DNA & RNA Purification

Amid Biosciences’ silica coated magnetic particles - SilaMag Microparticles - produced by employing a modified Stoeber process by hydrolysis of orthosilicates on magnetite surface. Silica coating improves stability and shelf life of the magnetic microparticles. The surface of SilaMag Microparticles contains terminal Si-OH bonds facilitating hydrophilic properties. Additionally, Si-OH bonds enable the surface functionalization by offering diverse active groups including NH2, COOH, SH, N-hydroxysuccinimide (NHS) and epoxy for the covalent binding of proteins, antibodies, DNAs, RNAs and other molecules.      Properties:  SilaMag Microparticles are stable in water and common buffers, and in presence of detergents.  Specification: Size: 2 - 3 um Concentration: 50 mg/ml pH: 7.0 Density: 1.3 g/ml  Applications:  SilaMag Microparticles allow quick separation from solution. clean-up and size exclusion procedures, plasmid DNA extractions, isolation of total nucleic acids from mammalian cells
