Glycoprofile of PrPres in RLN samples analyzed in scrapie and BSE infected sheep. Triangular presentation of the proportion of each of three glycoprofile components per individual RLN sample. Symbols correlate with group of sheep: ● – field cases, ◯ – scrapie cases in preclinical study (excluding 2 clinical cases), ▲ – sheep with experimental BSE, △ – sheep in preclinical stage of experimental BSE. The average and SDs per group is indicated by respectively the larger size symbols and bars. The small triangle diagram indicates in which direction from the axes each point should be read.
