Comparison of difference in Hp levels in serum between healthy controls and scrapie infected sheep from six to 23/24 weeks of age. Scrapie (red dots), controls (blue dots), haptoglobin (Hp) levels measured in mg/ml indicated on y-axis and groups are presented on the x-axis. Each sample is individually plotted (four control samples and five scrapie samples), but, at some time points, the dots appear as one single measurement due to very similar values and the scale accommodates the scrapie measurements, as they show more variation and a higher levels.
