Supplementary Figure 2: Impaired Erk phosphorylation in T cells generated in the β5t-deficient thymus.

ERK1 and 2 phosphorylation in response to OVAp–H-2K^b tetramer stimulation was examined in CD44^loCD8⁺ OT-I-TCR-transgenic T cells at indicated time. Representative data from two independent experiments are shown.
