1 = UPIN: Unique Patient Identification Number (sera obtained from patients vaccinated as shown in Table 4).
2 = Predominant plant glycan type. V, vacuolar, with major species indicated; S, secretory, with major species indicated. A = galactose; Gn = N-acetyl glucosamine; M = mannose; F = fucose; X = xylose.
3 = HRP, horseradish peroxidase, a plant enzyme containing complex plant-type glycans used as a control.
4 = Irrelevant plant-produced glycosylated human idiotypic Ig used as a control.
