nanomag®-D particles with diameters of 130 nm, 250 nm and 500 nm (separation at a permanent magnet) are designed with amino groups on the surface for the covalent binding of proteins, antibodies or other molecules. The functionalized nanomag®-D particles are supplied in water without any surfactants.
Thus several conjugation methods can be applied, e.g. maleimide or SPDP functionalization of the amino groups for conjugation of SH-labeled biomolecules (see Technote 201 and Technote 202)
