Studies on the denaturation of antibody. IV. The influence of pH and certain other factors on the rate of inactivation of Staphylococcus antitoxin in urea solutions

In previous work on the denaturation of antibody, studies have been made of some of the factors influencing the inactivation of diphtheria antitoxin in urea solutions (1, 2). A quantitative formulation of a simple kinetic theory was found to fit satisfactorily the experimental data and to offer a reasonable explanation of the deviation of the inactivation from simple first order behavior (2). In the present work we have studied the inactivation of Staphylococcus antitoxin, investigating the influence of certain new factors on the rate and course of the over-all reaction, with a view toward gaining further insight into the mechanism of the reactions, and reinvestigating the influence of pH, a factor studied previously with diphtheria antitoxin, in order to test the applicability of the proposed kinetic mechanism to different antibodies

Natural immunity, and natural antibody reactions

This thesis records the results of investigations into certain phenomena in natural immunity and natural antibody reactions. Many of the experiments were exceedingly complex and the tables of results are also, therefore, complex. Typical examples of the various phenomena encountered are expressed only once in order that the thesis be not overweighted with tables. Every step has been taken towards simplification of the expression of results. For this reason also, the thesis does not include any protocols of the experiments
