FIGURE 1

Analysis of carbohydrate epitopes in genetically modified pigs (54). Confocal microscopy of 2-month-old WT, 8-month-old GGTA1 KO, and 2-day-old GGTA1/CMAH double-KO porcine tissues stained with (A) anti-Neu5Gc chicken IgY (cyan, Sialix, Vista, CA, United States) and (B) IB4 lectin (red). (C) Flow cytometric analysis of PBMCs labeled with anti-Neu5Gc antibody (blue) and IB4 lectin (red). Unstained PBMCs were the negative controls for IB4 lectin, and an isotype negative control was used in the anti-Neu5Gc staining. Although shown, the negative controls are difficult to see in some panels because of overlap with the experimental group.
