Abstract
This study of globin and its compound with casein (globin caseinate) shows that globin fails to produce fixation antibodies in rabbits after repeated injections, thus agreeing with our own work and with that of others with similar histon bodies which are primarily toxic. When globin is combined with casein, however, it gives rise to antibodies that react not only with globin caseinate and casein but also with globin. The antibodies in antiglobin casein serum are apparently separate, one for globin and one for casein. In other words, the change in globin undergone on combination with casein has apparently rendered it antigenic. We did not succeed in demonstrating the genesis of this new antigenic property by anaphylaxis experiments. A further investigation of similar and more complex combined proteins is indicated and gives promise of more light on the nature of biological specificity.
