  • Patent number: 7553938
    Abstract: A method of preparing a purified, virus inactivated and virus safe antibody preparation from a starting solution comprising antibodies and contaminants, the method comprising the steps of: (a) adjusting the pH of the starting solution to about 4.6 to about 4.95 in particular to about 4.8 to about 4.95 to produce an intermediate solution; (b) adding caprylate and/or heptanoate ions to the intermediate solution and maintaining the pH at about 4.6 to about 4.95 in particular pH at about 4.8 to about 4.

  • Publication number: 20020035241
    Abstract: A process separates and/or isolates plasma proteins, especially human plasma proteins, from a mixture containing plasma proteins, wherein the mixture is applied to a separation medium having an annular design and having a layer of application medium applied thereon; the separation medium having the annular design is rotated essentially vertically about an axis which is defined in the direction of flow of the mixture through the separation medium having the annular design; an eluent is passed through the separation medium having the annular design; and fractions exiting at the end of the separation medium having the annular design are collected.

  • Patent number: 6268484
    Abstract: Disclosed are antibodies which can be used for the manufacture of vaccines for active and/or passive immunization of persons in need of such treatment. The invention also provides for human monoclonal antibodies that are functionally equivalent to the above-mentioned antibodies produced by any one of the cell lines CL1 through CL6 (deposited at the European Collection of Animal Cell Cultures (ECACC) at the PHLS in Porton Down, Salisbury, UK). Also provided are hybridoma and/or CHO cell lines producing any one of the antibodies disclosed and claimed herein, Also provided are mixtures of antibodies of the present invention, as well as methods of using individual antibodies or mixtures thereof for the detection, prevention and/or therapeutical treatment of HIV-1 infections in vitro and in vivo.

  • Patent number: 6057164
    Abstract: The method for the aptitude testing of protein fractions containing factor VIII the further processing of which comprises a pasteurizing step is performed in such a way that the starting material is examined for fragments within a range of from 20 to 50 kD. Fragments of factor VIII within this range evidently cause inhibitor formations in patients pretreated with factor VIII. Batches contaminated with such fragments can also be utilized, i.e., for the preparation of a high purity virus-free factor VIII by size exclusion chromatography on hydrophilic materials.
