Figure 2. Binding specificity of human and avian synthetic receptors.

Figure 2

ELISA plates were coated with either (A) the human α2,6-sialyllactoside-MSA receptor or (B) the avian α2,3-sialyllactoside-MSA receptor. Various types of recombinant HA proteins were tested. The binding of each recombinant HA to either receptor was detected with strain-specific antibodies and Uni-1 Abs which are universal antibodies against all HA proteins. Binding is shown as mean of absorbance from three experiments with error bars indicating the standard deviation.
