Production of Epitope-Specific Antibodies by Immunization with Synthetic Epitope Peptide Formulated with CpG-DNA-Liposome Complex Without Carriers.

Antibody production using synthetic peptides has been investigated extensively to develop therapeutic antibodies and prophylactic vaccines. Previously, we reported that a complex of CpG-DNA and synthetic peptides corresponding to B cell epitopes, encapsulated in a phosphatidyl-β-oleoyl-γ-palmitoyl ethanolamine (DOPE):cholesterol hemisuccinate (CHEMS) complex, significantly enhanced the synthetic peptide-specific IgG production. Here, we describe synthetic peptide-based epitope screening and antibody production without conventional carriers.
