The Kinetics of Heat Inactivation of Bovine Serum Agglutinins for Brucella

Abstract
Two types of nonspecific agglutinins for Brucella were distinguished from specific agglutinins by their rates of heat inactivation. Measurements of the rate of loss of agglutinin activity disclosed that inactivation was a first order reaction. The 3 types of agglutinins for Brucella may be distinguished by comparing results of agglutination tests incubated at 56[degree]C (18 hours) and at 65[degree]C (15 minutes).
