in Lösung bringen.
Beispiel l.
100 Teile nukleinsaures Natrium aus Hefe werden in 300 Teilen Wasser gelöst und unter rmriihren mit einer Lösung von 40 Teilen Silbernitrat in Wasser versetzt. Es entsteht ein dicker Brei, zu welchem man, nach und nach solange eine gesättigte Kochsalzlösung hinzugiebt, bis eine klare Lösung entstanden ist. Dieselbe wird dann mit Alkohol gefällt, der Niederschlag mehrmals mit Alkohol gewaschen und im Vakuum getrocknet. Das neue Produkt bildet ein gelblich weisses in Wasser mit gelblich brauner Farbe leicht lösliches Pulver, welches ca. 22-23% Silber enthält. Es i-t unlöslich in Äther und Benzol.
Beispiel 2.
50 Teile nukleinsaures Natrium aus Thymus werden in 150 Teilen Wasser gelöst und mit einer Lösung von 19, 5 Teilen Silbernitrat in 60 Teilen Wasser versetzt. Zu dem entstandenen Brei giebt man darauf langsam eine wässerige Natriumazetatlösung bis wieder Klärung erfolgt ist und verarbeitet die so erhaltene Lösung nach eventuellem Filtrieren, wie in Beispiel 1 angegeben. Das so erhaltene Produkt gleicht in seinen Eigenschaften dem in diesem Beispiel-be- schriebenen Produkt.
Beispiel 3.
100 Teile der nach Beispiel 1 der deutschen Patentschrift Nr. 139907 dargestellten Formal- dehydverbindung der Nukleinsäure werden in 300 Teilen Wasser und unter Umrühren mit einer wässerigen Lösung von 40 Teilen Silbernitrat versetzt. Es entsteht ein dicker Niederschlag, der durch Zusatz einer gesättigten Kochsalzlösung wieder in Lösung gebracht wird. Aus dieser Lösung wird durch Fällen mit Alkohol oder Eindampfen im Vakuum die Silberverbindung der Formal-

bring into solution.
Example l.
100 parts of sodium nucleic acid from yeast are dissolved in 300 parts of water and, while stirring, a solution of 40 parts of silver nitrate in water is added. The result is a thick paste to which a saturated saline solution is gradually added until a clear solution has formed. The same is then precipitated with alcohol, the precipitate washed several times with alcohol and dried in vacuo. The new product forms a yellowish white powder which is easily soluble in water with a yellowish brown color and which contains approx. 22-23% silver. It is insoluble in ether and benzene.
Example 2.
50 parts of sodium nucleic acid from thymus are dissolved in 150 parts of water, and a solution of 19.5 parts of silver nitrate in 60 parts of water is added. An aqueous sodium acetate solution is then slowly added to the resulting pulp until it has become clear again, and the solution obtained in this way is processed as indicated in Example 1 after filtering, if necessary. The product obtained in this way has the same properties as the product described in this example.
Example 3.
100 parts of the formaldehyde compound of the nucleic acid shown in Example 1 of German Patent No. 139907 are mixed with an aqueous solution of 40 parts of silver nitrate in 300 parts of water and while stirring. A thick precipitate is formed, which is brought back into solution by adding a saturated saline solution. From this solution, the silver compound of the formal-

on. It contains about 22% silver.
