CHEMICAL STUDIES ON BACTERIAL AGGLUTINATION : IV. QUANTITATIVE DATA ON PNEUMOCOCCUS R (DAWSON S)- ANTI-R (S) SYSTEMS.
1. The quantitative, absolute method of agglutinin estimation is extended to the reaction between Types I and II pneumococcus R (S) suspensions prepared in various ways and antisera from rabbits injected with these cells. 2. Quantitative estimations of the amount of antibody to pneumococcus C substance are also given. 3. The significance of the data is discussed.
