     Die bisher bekannten Methoden,   natives Eiweiss in Lösung zu bringen, sei es durch Alkali, sei es durch Säuren, führten immer schon zu einer   Veränderung   desselben, und das aus   diesel lösungen   durch Fällen regenerierte Eiweiss erwies sich nicht   mphr als (ler     ursprüngliche Körper.   Nach den Untersuchungen von   öfete   ist ein   ausgexeichnetes Lösungs-   mittel für Eiweisskörper Thiosinamin (Allylsulfoharnstoff) in wässeriger Lösung. Behandelt

   Lösung übergeht.   Durch Filtration kann man dann das Eiweiss leicht trennen.

   Es   bat sich   nun gezeigt, dass man dieses Verhalten des   Eiweiss gegenüber   dem Thiosinamin und Alkohol benutzen kann, um dasselbe aus frischen Organen ohneweiters herauszuziehen. Man

 gegriffenen Rückstand zu befrien und das Filtrat mit Alkohol respective Alkohol und   Ather zu   versetzen. Sofort fällt das Eiweiss und die eiweissartigen Körper in Flocken aus und können dann leicht durch Filtration von der   alkoholischen     Thiosinaminlösung   getrennt werden. Das Thiosinamin gewinnt man aus der alkoholischen Lösung durch Abdestillieren des alkohols und Umkrystallieren des Rückstandes leicht wieder rein   zurück.   



   Beispiele 1. 



   Man verreibt frische Thyreoidea zur besseren Vertheilung mit dem gleichen Gewichte said, versetzt mit dem ungefähr dreifachen Gewichte Thiosinamin und dem gleichen Gewichte   Wasser, worauf man einige Zeit erhitxt. Dabei geht   ein grosser Thoil in Lösung, welche   man von dem Rückstande trennt. Durch   Versetzen des Filtrates mit dem mehrfachen Volumen Alkohol und Äther wird das Eiweiss als flockiger Niederschlag ausgefällt, welches   man   durch Waschen mit Alkohol weiter reinigen kann. Durch nochmalige Behandlung mit   Thiosinamin   kann man auch die letzten Spuren von Verunreinigungen abscheiden.

 EMI1.1
 



     The previously known methods of bringing native protein into solution, be it with alkali or with acids, have always led to a change in the same, and the protein regenerated from these solutions by precipitation did not prove to be the original body According to Oefete's studies, an excellent solvent for protein bodies is thiosinamine (allyl sulfourea) in aqueous solution

   Solution passes. The protein can then be easily separated by filtration.

   It has now been shown that this behavior of the protein towards thiosinamine and alcohol can be used to extract the same from fresh organs without further ado. Man

 to free the seized residue and to add alcohol or alcohol and ether to the filtrate. The protein and the protein-like bodies immediately precipitate in flakes and can then easily be separated from the alcoholic thiosinamine solution by filtration. The thiosinamine is easily recovered from the alcoholic solution by distilling off the alcohol and recrystallizing the residue.



   Examples 1.



   Fresh thyroid gland is rubbed in with the same weight for better distribution, added about three times the weight of thiosinamine and the same weight of water, after which it is taken for a while. A large thoil goes into solution, which is separated from the residue. By adding several volumes of alcohol and ether to the filtrate, the protein is precipitated as a flaky precipitate, which can be further purified by washing with alcohol. By repeated treatment with thiosinamine one can also remove the last traces of impurities.



   ExampleII.



   Fresh liver is rubbed with the same weight of sand for better digestion and then treated with thiosinamine in the manner given in the previous example.
