  • Patent number: 9200032
    Abstract: A process for obtaining an IgG composition involves heat treatment. This process obtains an IgG composition from an IgG solution partly purified from human plasma, in which by applying intermediate heat treatment and without using reagents to precipitate high molecular weight aggregates/polymers and/or proteins virtually total elimination of the IgG polymers generated during the process is achieved. Furthermore this process offers high productivity, lower production costs and is easy to implement in comparison with the processes of the know art. In addition to this, by using this process stability is imparted to the final product in liquid.

  • Patent number: 8231599
    Abstract: A process for detoxifying the blood of a patient in need thereof involves: collecting albumin from human plasma and/or plasma fractions; diafiltration of a mixture containing the collected albumin; stabilizing the resulting diafiltered albumin mixture with sodium chloride and an amino acid in the absence of any added fatty acid; pasteurizing the stabilized albumin mixture; diafiltering the pasteurized mixture to remove, among other things, stabilizers; and detoxifying the blood of the patient by administering the resulting albumin to the patient. In one embodiment, the amino acid stabilizing agent is acetyl tryptophan. The resulting albumin has at least about 80% albumin binding capacity relative to natural plasma albumin, and is storage stable for about 30 months at 30° C.

  • Patent number: 6875848
    Abstract: The gammaglobulin is extracted from a fraction isolated by fractionation with ethanol in the presence of a carbohydrate, and after reducing the content of contaminants with PEG, it is applied to an anionic resin exchange column, an effluent being obtained in which the PEG content is subsequently reduced by ultrafiltration and which is concentrated in order to carry out sequentially an optional treatment at an acid pH and at least one of the following steps of viral inactivation, consisting of pasteurisation and a treatment with solvent/detergent, the product afterwards being precipitated and washed with PEG in order to eliminate any chemical viral inactivation reagents and then, by solubilisation and change of pH, the protein contaminants, and finally purified by ultrafiltration to reduce the volume and the PEG content, then carrying out an optional virus filtration and subsequent concentration.
