摘要:
A process for preparing a hemostatically active preparation containing von Willebrand factor (vWF) from a fraction of human plasma by chromatographic purification of a vWF-containing plasma fraction on an anion-exchange material which has the anion-exchanging groups on grafted polymeric structures (tentacle materials), collecting a vWF-containing fraction, followed by purification of said fraction using gel permeation to prepare a purified thermally stable vWF-containing preparation; and heating the preparation for inactivating viruses.

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:
The invention relates to Inter-alpha inhibitor proteins (IαIp). The invention further relates to processes for purification of IαIp compositions and their use for treatment of human diseases such as sepsis and septic shock, rheumatoid arthritis, cancer and infectious diseases.
摘要:
A porous self-supporting structure comprising at least two porous components A and B and the porous component B embraces the porous component A, wherein (i) surfaces of pores of the at least two porous components A and B are provided with chemical moieties for interaction with substances passing the pores and (ii) the pores of the porous components comprise a uniform multimodal pore size distribution through the entire polymeric structure.

Disclosed is a process for preparing agents containing virus-inactivated vitamin K-dependent plasma components as well as protein C, protein S, factors II, VII, IX and/or X as well as combinations thereof, such as, for example, PPSB preparations, wherein a source containing these components is subjected to a appropriate separation procedures, especially by using membrane-chromatographic methods.
摘要:
A device for the rapid separation and/or conversion of substrates is disclosed herein. The device include a porous tube (2) disposed inside a tubular sample distributor (3). The tubular sample distributor (3) includes channel structures on its inner surface and is disposed inside a tubular body (4). A tubular sample collector (1) having channel structures on its outer surface is disposed inside the porous tube (2). A circular sample distributor (7) is provided having a circumferential portion and radially extending grooves in conjunction with the channel structures of the tubular sample distributor (3). A circular sample collector (8) is also provided having a circumferential portion and radially extending grooves in conjunction with the channel structures of the tubular sample collector (1). The hollow body (4) is arranged between securing means (5) that provide a sample inlet and outlet in communication with the circular sample distributor (7) and circular sample collector (8), respectively.
摘要:
An apparatus for the conversion of substrates both for analytical and preparative purposes in a flow-through and cross-flow reactor having compact porous discs and/or compact porous tubes as carrier for conversion reaction or preparative separations which compact porous discs and/or compact porous tubes are modified with substances being capable of specifically binding and/or converting said substrates by distributing the samples to be converted and/or preparatively separated and collecting the converted and/or separated substrates preferably in a low volume, wherein the distribution of the sample does not affect the carrier adversely.
