Abstract Background Conserved neutralizing epitopes are considered to be a key role for eliciting broadly neutralizing antibody NAb . Previously two conserved neutralizing epitopes of HIV-1 CRF01_AE envelope were identified at amino acid 93-112 of the C1 C1E and at 218-239 of the C2 C2E regions. To access the potency of antibody directed against conserved epitopes a monoclonal antibody MAb specific to the C2E region was developed and characterized. Methods The immunogenicity of two epitopes was examined by immunizing BALB c mice with the matching synthetic peptides. One MAb C2EB5 directed against peptide C2E was generated by .
