  • Patent number: 5019402
    Abstract: There is disclosed a composition and process for disinfecting or essentially sterilizing blood fractions and components of blood. The composition is formed by adding a chlorine dioxide liberating compound with a weak organic acid and a heat activated saccharide.
    Type: Grant
    Filed: February 20, 1990
    Date of Patent: May 28, 1991
    Assignee: Alcide Corporation
    Inventors: Robert D. Kross, David I. Scheer
  • Patent number: 4857514
    Abstract: A virus having a lipid-containing capsid, such as AIDS virus, is inactivated by contacting the virus with an inactivating amount of phosphatidyl choline. Such a virus can be inactivated in fluids such as virus-contaminated body fluids or derivatives, e.g., blood or blood derivatives. The phosphatidyl choline can be present in an Active Lipid (AL) composition further comprising neutral lipids and phosphatidyl ethanolamine. Phosphatidyl choline, and an AL composition containing same, is useful for the treatment or prophylaxis of Acquired Immune Deficiency Syndrome (AIDS) in mammals.
    Type: Grant
