TCR Vß chain collection of GCAA peptides-specific T cell clones. The clonality of T cell clones reactive tumoral antigen peptides was analyzed by a panel of 24 monoclonal antibodies specific for human TCR Vß chain families, as detailed in “Materials and methods”. T cell blasts from each clone were divided in aliquots and stained with each of the monoclonal antibody and the appropriate isotype controls
