摘要:
A method for reduction of the viral infectiousness of potentially infectious material, such as human or animal body fluids or fractions derived therefrom from which biologically active substances can be isolated, wherein the infectiousness is due to non-lipid-coated viruses characterized in thatsaid potentially infectious material for the isolation of said biologically active substances is treated witha hydrophobic phase which is essentially insoluble in water and is capable of forming a two-phase system with said potentially infectious material, andsaid hydrophobic phase is separated from the potentially infectious material thus treated.

摘要:
A method for the inactivation of viruses, in particular those having no lipid coats, in protein-containing compositions from blood, blood plasma or similar natural sources by treating said source, simultaneously or succesively, with an effective amount of dialkyl or trialkyl phosphates and optionally surfactants at an elevated temperature in the range of from 55° C. to 67° C. for five hours to 30 hours.
摘要:
A stable, injectable solution containing factor VIII suitable for the treatment of humans, natural or synthetic disaccharides, preferably saccharose, in concentrations of from 0.1 to 0.65 mol/1, and one or more amino acids in concentrations of from 0.1 to 1.0 mol/1. A process for preparing same and the use of natural or synthetic disaccharides, preferably saccharose, and one or more amino acids for stabilizing factor VIII.
摘要:
What is disclosed is a process for rendering plasminogen virtually free of hepatitis virus by heating a plasminogen solution in the presence of a proteinase inhibitor with plasmin specificity, an amino acid, and a saccharide or sugar alcohol.
摘要:
What is disclosed is a method for making a preparation containing blood clotting Factors IX and/or X virtually hepatitis-safe by warming said peparation in the presence of calcium ions and in the further presence of an amino acid and/or a saccharide or sugar alcohol.
摘要:
What is disclosed is a method for treating a preparation containing blood clotting Factors II and/or VII to render it virtually hepatitis-free by warming said preparation in the presence of a chelating agent and in the further presence of an amino acid and/or a saccharide or sugar alcohol.
摘要:
Described is an economical process for the recovery of factor VIII from blood plasma or cryoprecipitate. In the process, anion exchanger chromatography is conducted using a separating material based on carriers containing hydroxyl groups, the surfaces of which carriers have been coated with covalently boded polymers. The polymers contain repeating units represented by formula (I). ##STR1##
摘要:
A process for purifying liquids containing blood clotting factors by adsorption of the factors on mineral adsorbents such as calcium phosphate, aluminum hydroxide gel, barium sulfate or hydroxylapatite in the presence of calcium ions followed by elution is described.
