    • In the preparation of parenteral solutions for the therapy and prophylaxis of thromboses and embolisms, because of the poor solubility of t-PA hitherto either the infusion of very large volumes has been necessary, or else a solution with a low volume and a high t-PA concentration has been prepared at the expense of setting up a non-physiologically low pH of 2 to 5.Hence, the present invention relates to a process for the preparation of a solution of high concentration of a protein having plasminogen activator activity, where an increase in stability and solubility is achieved by adding at least two substances from the group of D- and/or L-amino acids, their salts, derivatives or homologs. This invention also relates to a process for the pasteurization of a protein solution having t-PA activity, and to a t-PA-containing solution prepared by the claimed process, and to the use of this solution as a fibrinolytic in human and veterinary medicine.
    • 在制备用于治疗和预防血栓栓塞和肠栓塞的肠胃外溶液中,由于t-PA的溶解性差,所以必须输入非常大的体积,或者是具有低体积和高t- 已经以建立2至5的非生理学低pH为代价制备了PA浓度。因此,本发明涉及一种制备高浓度具有纤溶酶原激活剂活性的蛋白质的溶液的方法,其中 通过从D-和/或L-氨基酸,其盐,衍生物或同系物组中加入至少两种物质来实现稳定性和溶解度的增加。 本发明还涉及一种用于将具有t-PA活性的蛋白质溶液巴氏杀菌的方法以及通过所要求保护的方法制备的含有t-PA的溶液的方法,以及该溶液在人和兽医学中作为纤维蛋白溶解剂的用途 。
