PEG-COOH

BNF-Dextran or BNF-Starch particles are available with PEG-COOH groups on the surface for the covalent binding of proteins, antibodies or other molecules. The matrix of the functionalized particles consists of crosslinked dextran or hydroxyethyl starch. The 100 nm particles can be separated with conventional permanent magnets, while the 80 nm particles have to be separated in high gradient magnetic fields. BNF particles can easily be filtered through 0.22 µm filters. They are supplied in water without any surfactants.
