Abstract

A detergent such as nonionic, cationic or anionic detergents and preferably a \"sugar detergent\" such as octyl-glucopyranoside is rendered insoluble by being bound to an inert substrate. This detergent is effective at inactivating pathogens even when so bound. Under these conditions the concentration of detergent free in solution is vanishingly low: probably below one millimolar in concentration. Addition of insoluble detergent results in effective destruction of enveloped viruses in a variety of protein containing solutions such as blood, plasma, clotting factors or other proteins purified from human blood. Because the detergent is essentially entirely bound to the solid substrate, there is little or no difficulty in ensuring that the end product is detergent-free. Because the detergent is so bound, it causes essentially no damage to proteins, blood cells and other cellular material.
