    摘要: A concentrated, immunoglobulin composition for treating subjects vaccinated against or infected with a pathogenic microorganism, is made by (a) selecting a population of individuals previously vaccinated against antigens associated with the pathogenic microorganism; (b) identifying very high titre individuals by determining the level of specific antibodies immunoreactive with the pathogenic microorganism in the blood of the individuals; (c) combining blood from the very high titre individuals; and (d) purifying and/or concentrating the product of step (c). A concentrated immunoglobulin composition can include specific antibodies immunoreactive with a pathogenic microorganism, wherein the titre of specific antibodies is at least 5 times higher than the average titre of specific antibodies of a population of individuals previously vaccinated against antigens associated with the pathogenic microorganism. The composition has a relatively high protein concentration and a low percentage of protein aggregates. The pathogenic microorganism is preferably smallpox virus or vaccinia virus.

    摘要: The invention relates to purification of an intact, non-degraded macromolecule from a biological mixture comprising the macromolecule in the presence of its lytic enzyme. The method comprises providing the biological mixture as a heterogeneous mixture comprising the lytic enzyme, at least partially, in soluble form and the macromolecule, at least partially, in non-soluble form; batch-wise contacting the heterogeneous mixture with an immobilized inhibitor of the lytic enzyme; increasing the solubility of the macromolecule in the mixture; and removing the immobilized inhibitor from the mixture.

    摘要: A method for micronization of a dispersion of particles including a protein having a predetermined level of biological activity, is provided. The method includes introducing the dispersion into a vortex chamber milling apparatus under milling conditions which result in a protein powder having a particle size distribution of 5 to 100 μm and/or exhibiting a 30 to 400 fold size reduction of the protein particle dispersion from its original size, and retaining at least 80% of the predetermined level of biological activity of the protein. The milling conditions include one or more parameters selected from the following: input pressure between 1 and 7 Bars; injector pressure between 0.2 and 5 Bars; loading rate between 0.1 and 5 kg/hour; and gas flow between 30 and 100 m3/hour.
