Abstract
Heparin covalently attached to a water-insoluble resin suspended in HIV-infected aqueous buffer or whole blood captures the virus; subsequent physical separation of the immobilized heparin reduced the viral titers by over 80 and 50%, respectively. The detoxification concept has been validated by both circulating an HIV-1 solution through a column packed with the heparin–sepharose beads and successively mixing an HIV-1 solution with fresh beads.
