Silica Coated Magnetic Nanoparticles | RNA Extraction

$ 70.00


 Amid Biosciences’ SilaMag Nanoparticles are produced by employing a modified Stoeber process by hydrolysis of orthosilicates on magnetite surface. Silica coating improves stability and shelf life of the magnetic NanoBeads.

The surface of SilaMag Nanoparticles 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.    


SilaMag Nanoparticles are stable in water and common buffers.


  • Size: ~ 400 nm
  • Concentration: 10 mg/ml
  • pH: 7.0
  • Density: 1.3 g/ml


SilaMag NanoBeads allow quick separation from solution.

  • clean-up and size exclusion procedures,
  • plasmid DNA extractions,
  • isolation of total nucleic acids from mammalian cells,
  • gDNA extraction,
  • RNA from mammalian cells,
  • methylated DNA extraction.


Suspension in water. The suspension should be stable approximately one year stored at 2-8 °C.

Precautions and Disclaimer

SilaMag Nanoparticles for laboratory use only; not for diagnostic, drug, household or other uses. Please refer to the Material Safety Data Sheet (MSDS).
