Description
Verfahren zur Verhinderung der Denaturierung in Wasser gelöster eiweißhaltiger Heilmittel Bekanntlich zeigen eiweißhaltige Lösungen die Eigenschaft, . daß sie nicht dauernd klar bleiben, sondern zur Flockenbildung neigen, was auf Denaturierung des Eiweißes beruht. Dieser -Umstand macht sich besonders bei therapeutischen Präparaten störend bemerkbar.Process for preventing denaturation of proteinaceous substances dissolved in water Remedies It is well known that solutions containing protein show the property. that they do not stay clear all the time, but tend to form flakes, which indicates denaturation of protein is based. This circumstance is particularly evident with therapeutic preparations noticeably disturbing.
Es wurde nun gefunden, daß man die Denaturierung und damit die Flockung von eiweißhaltigen Lösungen aufheben oder weitgehend verhindern kann, indem man den eiweißhaltigen. Lösungen höhermolekulare Eiweißabbauprodukte, insbesondere Säuren, wie Protalbinsäure, Lysalbinsäure usw., zugibt. Insbesondere sind die Salze dieser Eiweißabbauprodukte, besonders die Alkalisalze, für das Verfahren geeignet. Man führt das Verfahren zweckmäßig so aus, daß man die erwähnten Stoffe den fertigen Lösungen zugibt. Mit gleichem Erfolge können die die Flockung verhindernden Stoffe auch in einer beliebigen Stufe des Fabrikationsproz es,ses der eiweißhaltigen Lösung zugesetzt werden.It has now been found that the denaturation and thus the flocculation of protein-containing solutions can be eliminated or largely prevented by the protein-rich. Solutions of high molecular weight protein degradation products, especially acids, such as protalbic acid, lysalbic acid, etc., adds. In particular, the salts are these Protein breakdown products, especially the alkali salts, are suitable for the process. Man expediently carries out the process in such a way that the substances mentioned are finished Admits solutions. The substances preventing flocculation can be equally successful also in any stage of the manufacturing process of the protein-containing solution can be added.
Es ist zwar bekannt, daß höhermolekuilare Eiweißabbauprodukte die Eigenschaften von Schutzkolloiden besitzen und beispielsweise die Fähigkeit haben, Sole von Metallkolloiden vor der Ausflockung zu schützen. Weiterhin ist es bekannt, in Wasser unlösliche oder schwer lösliche Eiweißverbindungen durch den Zusatz hydrotropisch wirkender Körper in wässerige Lösungen zu überführen. Die Möglichkeit, die Denaturierung von in wässeriger Lösung befindlichem Eiweiß durch den Zusatz von höhermolekularen Eiweißabbauprodukten zu verhindern, ist demgegenüber jedoch neu und überraschend. Beispiele i. Eine i %ige Thyreoglobulinlösung wird nach dem Zusatz eines Sterilisierungsmittels. mit i 0,'o protalbinsaurem Natrium unter Umrühren versetzt. Die Lösung zeigt nach dem Filtrieren keine Flockenbildung mehr.It is known that protein degradation products of higher molecular weight are the Have the properties of protective colloids and, for example, have the ability To protect brine from metal colloids from flocculation. It is also known Protein compounds that are insoluble or sparingly soluble in water due to the addition of hydrotropic to transfer the acting body into aqueous solutions. The possibility of denaturation of protein in aqueous solution through the addition of higher molecular weight However, preventing protein breakdown products is new and surprising. Examples i. A i% thyroglobulin solution is after the addition of a sterilizing agent. with i 0, 'o sodium protalbinate while stirring. The solution shows no more flocculation after filtering.
2. Eine fraktionierte Thyreoglobulinlösung wird auf die gewünschte Konzentration eingestellt und mit so viel protalbinsaurem Natrium versetzt, daß die Lösung i 0 o0 davon enthält. Die Lösung wird nunmehr mit Trikresol sterilisiert und durch Seitzfilter geklärt.2. A fractionated thyroglobulin solution is added to the desired Concentration adjusted and treated with so much protalbinate sodium that the solution contains i 0 o0 thereof. The solution is now sterilized with tricresol and clarified by Seitz filters.
3. Trockenpulver von Inselhormon wird nach dem Ergebnis der Standardisierung mit Alkalialbuminat vermischt und die Substanz allmählich in der berechneten Menge sauren Wassers aufgelöst, so daß eine an Alkali= albumin.at r°/QOige Lösung entsteht. Nach denn'-Filtrieren erhält man eine beständige, keine' Flocken bildende Lösung. ' _3. Dry powder of islet hormone is made according to the result of standardization with Alkali albuminate mixed and the substance gradually in the calculated amount of acidic water, so that an alkali = albumin.at r ° / QOige Solution emerges. After filtering, a consistent, no 'flake is obtained forming solution. '_
