micromer® particles are designed with amino groups on the surface in the whole size range of 25 nm to 100 µm. The particles are stable in aqueous media and to some extend in DMSO. The particles are supplied in water without any surfactants. Thus the whole variety of conjugation methods for the covalent binding of proteins, antibodies or other target molecules can be applied, e.g. maleimide or SPDP functionalization of the amino groups for conjugation of SH-labeled biomolecules.
