TCRαβ surface expression of the TCRα/β-deficient Jurkat clone 76 transduced with chimeric TCRs. Jurkat clone 76 was transduced with the TCR α chain of clone HA2.5 in combination with the TCR β chain of clone HA2.5, HA2.6, HA2.19, or HA2.20. The different subpopulations (dashed line indicates double marker gene negative; stippled line, single marker gene positive; or solid line, double marker gene positive) were gated and the TCRαβ expression was shown as histogram plots.
