The sera at Week 30 from rabbits immunized with KNH1144 immunogens were analyzed. The result represents the reciprocal of the dilution that inhibits mAb-mediated virus by 50%. The serum titers are color-coded as in Table 1. Titers for self-competition Ab represent the concentration which inhibits mAb-mediated virus by 50%. The Ab titers are color-coded as follows: white boxes (titer > 10 μg/ml for mAbs or < 20 for sera), yellow boxes (titer = 0.11-10 μg/ml for mAbs or 20-1000 for sera), and red boxes (titer ≤ 0.1 μg/ml for mAbs and > 1000 for sera).
