Interaction assessment between HA7 protein and its receptors. (a) Expression levels of the HA7 protein in 293 T cells, detected by Western blot; (b) Quantitative detection of HA binding to 3′SL- (b-1) or 6′SL-labeled receptors (b-2) by measuring KD values. (c) Quantification of NA activity was determined by measuring optical density generated in the chromogenic reaction
