摘要:
There is disclosed a highly purified complex comprising the components factor VIII and vWF having a specific activity of at least 70, preferably 100 to 300 U factor VIII:C/mg, a stable pharmaceutical preparation containing this complex as well as a method of producing the same.
摘要:
A thrombin of human or animal origin is free of infectious agents and is produced by activation of prothrombin subjected to a heat treatment for the inactivation of infectious agents.
摘要:
A method of inactivating viruses in blood products is described, wherein the blood products are heat-treated in a humid or in a solid state in the presence of inorganic or organic hydroxyl group-containing compounds having an H.sup.+ -dissociation constant of
摘要:
There is disclosed a method of determining the presence of incompatibility-reaction-causing substances in blood products. There is also disclosed a method of inactivating incompatibility-reaction-causing substances in blood products to be applied therapeutically and prophylactically. For this purpose, a fraction obtained from human or animal blood is treated with pancreas enzymes bound to water insoluble carrier material and, optionally, the fraction is subjected to further fractionation and concentration.

摘要:
A method of inactivating reproductive filterable pathogens in immunoglobulin-G-containing blood fractions to be applied therapeutically or prophylactically. In order to preserve full activity of the blood products and to completely inactivate pathogenic viruses, an aqueous solution of an immunoglobulin-G-containing fraction obtained from human blood is treated with neutral hydrolases at a temperature of 4.degree. to 50.degree. C. and at a pH of 5.5 to 9.5.
摘要:
A blood product, exclusive of albumin, inactivated relative to infectious agents, the blood product conforming to a total virus reduction factor of at least 40, having a biological acitity of at least 50%, based on its activity prior to effecting inactivation of the infectious agents, the blood product being producible from conventional blood products and being virus-safe.
摘要:
This invention is directed to a method of evaluating viral reduction capability of a viral inactivation step in a viral inactivation procedure. The method requires spiking a biological product with a virus more than once during the viral inactivation step so that a virus reduction factor can be calculated.
摘要:
A stable, highly concentrated intravenously tolerable immunoglobulin preparation is described having an immunoglobulin content from 13.5 to 17.5% (w/v), an osmolarity from 250 to 600 mOs/l and a viscosity of no more than 9 cP. The immunoglobulin preparation possesses an exceptional imperishability and also is used as a highly concentrated preparation without problems due to its low viscosity.
摘要:
A method of dissolving venous thrombi using a thrombolytic, parenterally administrable drug containing activated protein C is described. The drug can be free of serum amyloid P, thrombin activity, infectious agents and antibodies against protein C and activated protein C.
