Studies on the chemical basis of the antigenicity of proteins. 1. Antigenicity of polypeptidyl gelatins

Most proteins have been tested for antigenicity, and practically all have been found to be antigenic, though to a varying extent. Although antigens of non-protein nature are also known, the proteins seem to be the most abundant and important antigenic substances yet studied. It is the purpose of this series of investigations to try to establish some correlation between the chemical nature of the protein antigens and their immunological activity.
