TCR Vβ chain repertoire of cross-reactive gastric T cell clones. The clonality of T cell clones reactive to both H+,K+-ATPase and H. pylori lysate was analyzed by a panel of 22 monoclonal antibodies specific for human TCR Vβ 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.
