Patent number: 6150151Abstract: An affinity chromatographic matrix for purification of a biological material is provided having an ionically charged polymeric ligand such as glycoaminoglycan non-covalently bound directly by an ionic bond to an oppositely ionically charged group on a chromatographic matrix. Having the ligand non-covalently bound to the matrix by an ionic bond, allows the ligand to be easily washed off the matrix and replaced for subsequent purifications without having to replace the matrix. A biological material in a crude mixture is purified by non-covalently binding the material to the bound ligand and dissociating the material from the ligand. Matrices that may be used include crosslinked agarose, crosslinked dextran, crosslinked cellulose, crosslinked dextran and bisacrylamide, or matrices based on silica or plastic polymers. The charged group may be a quaternary amine or diethylaminoethyl group.Type: GrantFiled: August 17, 1994Date of Patent: November 21, 2000Assignee: American Cyanamid CompanyInventor: Kiran Manohar Khandke
