Abstract

A conjugate of a protein carrier and an antigen is disclosed. The carrier protein is cationized and the conjugate has enhanced immunogenic properties over those of the antigen alone. Cationization can be accomplished by derivatization of native carboxyl groups on the protein with an aklyl diamine, e.g. ethylene diamine, resulting in the formation of side chain aminoalkylamide groups, e.g. aminoethylamide.
