  • Patent number: 6429192
    Abstract: The starting material for the present purification process is a supernatant, suspension, milk product, colostrum or crude plasma protein fraction containing MBL. The starting material is subject to few pre-processing steps in order to obtain an MBL containing solution. By this it is possible to perform an affinity chromatography as the first chromatographic process step employing a non-conjugated polysaccharide matrix, from which MBL of a high purity is eluted. Besides constituting the major purification step of the process, the affinity chromatography also serves as a virus-removal step. In the production process of a virus-safe product, a virus-inactivation step is also included. The product of the process of the present invention is ready for use as medicinal product.

  • Publication number: 20020094336
    Abstract: The present invention is based on the identification and characterization of a number of M. tuberculosis derived novel proteins and protein fragments (SEQ ID NOs: 2, 4, 6, 8, 10, 12, 14, 16, 17-23, 42, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72-86, 88, 90, 92, 94, 141, 143, 145, 147, 149, 151, 153, and 168-171). The invention is directed to the polypeptides and immunologically active fragments thereof, the genes encoding them, immunological compositions such as vaccines and skin test reagents containing the polypeptides. Another part of the invention is based on the surprising discovery that fusions between ESAT-6 and MPT59 are superior immunogens compared to each of the unfused proteins, respectively.

  • Publication number: 20010051708
    Abstract: The present invention relates to a process for purifying immunoglobulin G from a crude immunoglobulin-containing plasma protein fraction. Said process includes a number of steps of which the anion exchange chromatography and the cation exchange chromatography are preferably connected in series. An acetate buffer having a pH of about 5.0-6.0 and having a molarity of about 5-25 mM is preferably used throughout the purification process. The invention further comprises an immunoglobulin product which is obtainable by this process. The invention also relates to an immunoglobulin product which has a purity of more than 98%, has a content of IgG monomers and dimers of more than 98.5%, has a content of IgA less than 4 mg of IgA/l, and contains less than 0.5% polymers and aggregates. Said product does not comprise detergent, PEG or albumin as a stabilizer. The product is stable, virus-safe, liquid and ready for instant intravenous administration.
