An agent for the therapy or prophylaxis of disturbances of hemostasis, which contains tissue protein PP4, a process for the purification of PP4 by means of a hydrophobic adsorbent which is insoluble in water, and a process for the pasteurization of a solution containing PP4 in the presence of calcium ions and of at least one mono- or oligosaccharide or sugar alcohol and, where appropriate, of an amino acid, and the use of PP4, are described.

Insulin derivatives, a process for their preparation, and their use

The invention relates to a method for the purification of the a subunit of factor XIII by affinity chromatography, to a therapeutic composition containing the latter, and to the use of the therapeutic composition. Factor XIII has hitherto been purified either by methods which are technically very elaborate or else by use of toxic affinity chromatography materials. The invention has the aim of providing an improved method for the purification of the a subunit of factor XIII. Factor XIII is obtained according to the invention by a method in which the a subunit of factor XIII is reversibly bound to a matrix suitable for disulfide exchange reactions and is removed from the matrix by reaction with a reducing agent. The method according to the invention makes it possible to provide the biologically active a subunit of factor XIII in high purity.

A process for the purification of tissue protein PP4 which can be obtained from placenta is described. This process makes use of the property of binding to saccharide polysulfates or to sulfated sugars in the presence of calcium ions.
