Overlap in segment use among repertoires. Overlap in (a) V
gene segment and (b) VDJ
use among all repertoires. The percent overlap is grayscale-coded according to the key below each plot. In (b), the range at the lower end of the scale is expanded in order to show the four pairs with 11–20 percent overlap (see text). Abbreviations: ds-DNA, double-stranded DNA; gp120, HIV-1 gp120; Sp, Streptococcus pneumoniae serotype; fVIII, clotting factor VIII; HBsAg, HBV surface antigen; IIb/IIIa, glycoprotein IIb/IIIa; MAG, myelin-associated glycoprotein; PL, phospholipid; TPO, thyroid peroxidase. Species of origin are as in Table 1.
