DEAE-Separopore® 6B-CL is a weak anion exchanger with excellent flow capacities and a high capacity for binding and resolution of proteins of all pI values. bio-World's DEAE-Separopore® 6B-CL was prepared by covalent attachment of diethylaminoethyl (DEAE) to Separopore® 6B-CL. DEAE remains charged and maintains high capacity over a wide working range of pH 3 – 9. It is an excellent matrix for both analytical and preparative fractionation of proteins.
