Characterization of receptor binding properties. Four different sialylglycopolymers (light blue line with diamonds, 2,3-SL; dark blue line with squares, α2,3-SLN; orange line with triangles, α2,6-SL; red line with circles, α2,6-SLN) were coated onto plates and bound with different viruses. a, b, c, d, e, and f Represent the binding properties of A/California/4/2009(H1N1), A/Anhui/1/2005RG(H5N1), A/Brisbane/59/2007(H1N1), A/Environment/Fujian/85144/2014(H1N8), A/duck/Alberta/35/1976(H1N1) and A/swine/Iowa/15/1930(H1N1), respectively. The data shown are the mean ± SD
