Recognition of TACAs by glycan-specific IgG in PAD. Recognition of TACAs by pooled serum IgG, as screened on the CFG array and depicted as dendrogrammed glycan reactivity matrix based on ABR (A) or as a radial dendrogram based on RFU values (B). (C) Heat map presentation based on RFU values illustrating the reactivity of individual serum IgG to TACAs, as revealed by screening on the NCFGv2.
