Carboxyl Coated Magnetic NanoBeads - CarboxyMag NanoBeads

$ 70.00

Amid Biosciences’ CarboxyMag NanoBeads are produced by a modified radical polymerization of methacrylic acid on magnetite surface.

The surface of CarboxyMag NanoBeads contains terminal COOH bonds that 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.   


CarboxyMag NanoBeads are stable in water and common buffers, and in presence of detergents.


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


CarboxyMag NanoBeads allow quick separation from solution.

  • clean-up and size exclusion procedures,
  • total nucleic acid extraction,
  • isolation of total nucleic acids from mammalian cells,
  • gDNA extraction,
  • cells isolation
  • protein and antibody coupling using carbodiimide chemistry


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

Precautions and Disclaimer

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