CHEMICAL STUDIES ON BACTERIAL AGGLUTINATION : V. AGGLUTININ AND PRECIPITIN CONTENT OF ANTISERA TO HAEMOPHILUS INFLUENZA, TYPE B.
1. The quantitative, absolute methods of agglutinin and precipitin analysis previously developed for antipneumococcus sera have been shown to be applicable to horse and rabbit anti-influenza type B sera and plasmas. 2. With the aid of these methods and improved immunization schedules the antibody content of the rabbit sera has been increased five to ten times. 3. The method recommended for the purification of rabbit antipneumococcus antibody has also been found applicable to rabbit anti-influenza type B sera.
