摘要:
A process for stabilizing the coagulation factors II, VIII, XIII, antithrombin III and plasminogen against heat is described. The preparations obtained according to this process are practically free from coagulable fibrinogen.
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.
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:
The invention relates to an antihemophilic agent, which may contain factor VIII, but also factor IV, VII and X activities and to a process for its manufacture by extracting placentae with an aqueous hypotonic medium, increasing the density of the extract and obtaining the supernatant layer forming thereupon.
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.
