Multiple Antigenic Peptides (MAPs) are peptides that are branched artificially, in which Lys residues are used as the scaffolding core to support the formation ≤8 branches with varying or the same peptide sequences. Multiple Antigen Peptides have been used to produce antibodies for use in immunological studies. MAPs have a high molar ratio of the peptide antigen to the core molecule, and no carrier protein is needed to elicit an antibody response.
