Comparison of the sialoside receptor specificity of the HAs from H7 influenza viruses.

aMembers of each group are identified according to the graph number used in the microarray data in Figures 2 and 3 and correspond to numbers in the complete glycan list (Table S4).
bBinding of samples to glycan subclasses are qualitatively estimated based on relative strength of the signal for the data shown in Figures 2 and 3: strong (+++), weak (+), absent (−).
cN-glycolylneuraminic acid.

a 各组的样本依据图2和图3中微阵列数据（microarray data）所采用的图谱编号进行标识，且与完整聚糖列表（Table S4）中的编号一一对应。
b 基于图2与图3所示实验数据的信号相对强度，可对样本与聚糖亚类的结合情况进行定性评估：强结合（+++）、弱结合（+）、无结合（−）。
c N-羟乙酰神经氨酸（N-glycolylneuraminic acid）。
