Figure S4. TCRβ subunit expression in developing thymocytes from WT and CSN5/JAB1^del/del mice. (A) Surface and intracellular TCRβ subunit expression was assessed in gated thymocyte subpopulations from WT and CSN5/JAB1^del/del mice. (B) A fraction of mature thymocytes in CSN5/JAB1^del/del mice fails to express a rearranged TCRβ subunit. Electronic gating was performed on CD8⁺ SP thymocytes. Percentage values for the various subsets are shown in the respective quadrants. Shown is one representative experiment out of four performed.
