QUANTITATIVE STUDIES OF BRUCELLA PRECIPITIN SYSTEMS : I. PRECIPITATION OF HOMOLOGOUS ANTISERA BY BRUCELLA ENDOANTIGENS.
It has been shown that the precipitation by the endoantigens of the three species of brucella of their homologous antibodies may be described by equations developed from the law of mass action. The endoantigens may be used for the accurate calibration of brucella antisera. The nitrogen-containing constituent of the endoantigens does not always seem to be intimately connected with the ability to precipitate the specific antibodies.
