Agglutination activities of the WT and MA viruses in various red blood cells. Four types of chicken red blood cells (cRBCs) were used: a, cRBCs. b, α-2,3 cRBCs (treated with VCNA and resialylated with α-2,3 glycans). c, α-2,6 cRBCs (treated with VCNA and resialylated with α-2,6 glycans). d, desialylated(Desial) cRBCs (treated with VCNA). The HA titers showed the agglutination activities of the WT and MA in the four types of cRBCs. The reported values are presented as the means and standard deviations of three independent experiments.
