Abstract
We investigated the epitope specificity of different monoclonal antibodies recognizing the cancer testis antigen PRAME. Antibody 5D3 binds to the fragment of PRAME corresponding to 160–180 amino acid residues. Antibodies 6H8 and F11 bind to the fragment corresponding to 180–200 amino acid residues of PRAME. These antibodies retained the ability to recognize these PRAME fragments after chimerization.
