Abstract
- 1. Pneumococcal rabbit antibody treated with acid shows an increase of nitrogen precipitable by S.
- 2. A shift in the combining ratio occurs at the same time.
- 3. The ratio of mouse-protective value / N precipitated by S is lowered.
- 4. The complement-fixing quality of acid-treated sera is impaired or lost when the ratio of mouse-protective power / N precipitable is lowered. Loss of complement-fixing quality was also observed with antibody subjected to a process of partial peptic digestion.
- 5. The properties of causing capsular swelling and of eliciting passive anaphylactic shock are unimpaired in acid-treated sera.
- 6. The implications of these observations are discussed.
Footnotes
1 The technical part of this investigation was divided as follows: A. M. Moos is responsible for the chemical work, F. L. Clapp for the tests with mouse-protection and capsular swelling, and A. J. Weil for the remainder.
