Effect of hemagglutinin receptor-binding domain mutations in viral entry. (A) Sequence alignment of mutations generated. (B) Relative infectivity of pseudoviruses containing specified receptor-binding domain substitutions as measured by luciferase activity. Data is representative of repeated experiments displaying similar trends. Values are means of triplicate samples ± SD.
