Method of reducing or suppressing undesirable activities of biological pharmaceutical and biomedical products and materials.

摘要

A method of reducing or suppressing undesirable activities like pyrogenicity, hepatitis infectivity and clotting activation of biological, pharmaceutical and biomedical products and materials by prolonged contact with a solution or suspension from about 0.01 to about 20 % by weight of a non-denaturing nonionic amphiphile and separating said amphiphile from the resulting treated product or material by liquid phase separation.
