Ratio = %V_βn⁺:%V_β8.1/8.2⁺ T cells. Mean percentage of V_β8.1/8.2⁺ in the Spl and MCD T cells of C57BL mice was 19 ± 2 and 16.5 ± 0.4% respectively, and for BALB/c mice was 22 ± 1 and 23 ± 5%, respectively. Bold shows V_β ratios indicative of superantigen-mediated deletion. Mean and SD of three to seven replicate experiments are shown.
