Comparison of the reactivity of Sha31 and P4 antibodies in the Western immunoblot from sheep challenged with caprine scrapie and controls. Animal numbers are displayed under each bar; cap1-2 and bov 1–2 are naturally infected caprine classical scrapie (II142) and bovine classical BSE control samples respectively run in duplicates on different gels. The cut-off value of 2 for separation between classical scrapie and BSE is indicated by the brown line. Values above 5 are not to scale and are displayed above the respective bar. LF141 and FF141 sheep had antibody ratios above 2, similar to the bovine classical BSE control samples
