THE MECHANISM OF THE ABDERHALDEN REACTION : STUDIES ON IMMUNITY. I.
1. The Abderhalden reaction is specific. 2. The properties of serum on which it depends develop in experimental animals simultaneously with antibodies during the process of immunization. 3. It is impossible to observe by direct methods the presence of digesting ferments in the blood of immune animals. 4. The Abderhalden test may be resolved into two phases. A dialyzable substance appears in the second phase and is the result of the autodigestion of serum. 5. The autodigestion of serum in the Abderhalden test is due to the removal of antitrypsin from the serum by the sensitized substratum.
