PEG-NH2

nanomag®-D particles with diameters of 130 nm, 250 nm and 500 nm are designed with PEG-NH2 groups on the surface for the covalent binding of proteins, antibodies or other molecules. The functionalized nanomag®-D particles can be separated with perment magnets and 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).
