  • Method for reduction of the infectiousness of potentially infectious material
    Patent number: 6136865
    Abstract: A method for reduction of the viral infectiousness of potentially infectious material, such as human or animal body fluids or fractions derived therefrom from which biologically active substances can be isolated, wherein the infectiousness is due to non-lipid-coated viruses characterized in thatsaid potentially infectious material for the isolation of said biologically active substances is treated witha hydrophobic phase which is essentially insoluble in water and is capable of forming a two-phase system with said potentially infectious material, andsaid hydrophobic phase is separated from the potentially infectious material thus treated.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: October 24, 2000
    Assignee: Octapharma AG
