DEFINITION

Classification: 530/403

Protein is identified as a antigen, e.g., immunogenic carriers, etc.:

(under subclass 402) Subject matter in which the protein is reacted with another material and the protein is claimed or disclosed as an antigen.

(1) Note. The compound reacting with the antigenic protein may itself be a protein or polypeptide. All such compounds are conclusively presumed to belong in subclass 405, even though they may contain sulfur.

(2) Note. The typical patent in this and the indented subclasses is directed to the use of an antigenic protein as an immunogenic carrier for a hapten.
