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.
