Location of escape mutations in recent and early N2 NAs. The amino acid positions where changes have been selected by monoclonal antibodies (mAb) are indicated by the colored bars: green, X-7(F1) (RI/5+/57) escape mutants; blue, Tokyo/67 escape mutants, including escape mutants of Tokyo/67 selected by antibodies made against A/Jap/305/57 (H2N2) and A/Texas/77 (H3N2); red, Mem/31/98 (Sydney-like) escape mutants. Data for X-7(F1) and Tokyo/67 escape mutants are from references 1, 18, 21, 42, and 43).
