  • Patent number: 6403092
    Abstract: Activation of &agr;2-macroglobulin (&agr;2M) with a nucleophilic compound followed by incubation of the activated &agr;2M at elevated temperature with a biomolecule results in covalent incorporation of the intact biomolecule into the &agr;2M molecule, without the use of proteinases. The thus-formed structurally defined and stable complex may be used as an antigen for stimulating the immune response, for example, in the form of a vaccine. Enhanced antigen presentation of a particular biomolecule is provided, especially for those that are poorly immunogenic; reduction of the immunodominance of particular epitopes is also provided.
