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.

The invention relates to the use of viral inactivated-plasma cryoprecipitate concentrate (VIPCC) comprising a suitable fibronectin/fibrinogen ratio for treating a spine disease, disorder or condition such as intervertebral disc degeneration.
摘要:
The invention relates to a proteolytic enzyme which is capable of forming fibrin when it reacts with fibrinogen, a fibrin-glue kit and a fibrin-glue formulation comprising an enzymatically-permissive concentration of a visualization agent and to their use in methods for prevention and/or reduction of adhesions and/or methods for promotion of blood coagulation sealing or filling body surfaces.

The present invention is directed to a reinforced absorbable multilayered hemostatic wound dressing comprising a first absorbable nonwoven fabric, a second absorbable woven or knitted fabric, thrombin and/or fibrinogen.
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.
摘要:
The invention relates to an immunoglobulin composition reduced in thrombogenic agents and to methods for its preparation. One method comprises subjecting an immunoglobulin containing solution to a negative cation exchanger chromatography at a pH in the range of higher than 3.8 to equal to or lower than 5.3. The solution can also be subjected to a negative anion exchanger chromatography at a pH in the range of 7 to 8.2.
