EXPERIMENTS ON ANAPHYLAXIS TO AZOPROTEINS

Abstract

Experiments with azoproteins containing stereo-chemical isomeric groups of d- and l-tartaric acid showed well marked specificity of the anaphylactic reaction to these antigens, in conformity with the results of precipitin tests. Shock in these animals could be prevented by injection of azodye containing the specific groups. This phenomenon is ascribed to a desensitization.
