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

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.
