Methods of using multivalent MHC class II-peptide chimeras

摘要

The present invention provides a multimeric complex of at least two chimeric molecules, wherein the chimeric molecules comprise an immunoglobulin constant region element and two MHC elements wherein each MHC element is associated with a peptide, and wherein the chimeric molecules are covalently linked through a carbohydrate residue of the immunoglobulin constant region element by a polyalkylene glycol linker. Methods of making and using the multimeric complexes are also provided.
