Glycoforms of PrP
isolated from different species. Samples 1–5 represent ME7, sheep scrapie, mouse BSE, BSE and sporadic CJD respectively. Percentages of specific glycoform are shown as average + standard error for each species. Values shown were obtained from independent experiments with 7 ME7 samples, 8 sheep samples, 2 mouse BSE samples, 5 BSE samples and 5 sCJD samples. Bars represent percentage glycoforms of double, mono and non-glycosylated bands according to the insert.
