Glycoprofiles of the analysed PrP^res. Glycoprofiles of the 39 resistant prion proteins (PrP^res), obtained with antibody 94B4. The PrP possesses two, one or no carbohydrates attached. These three forms are found in various proportions in a given animal. Colours refer to the percentage of the diglycosylated form. The average glycoprofiles (with standard deviations) obtained with 94B4 for a reference isolate of H-type and L-type are indicated (H_C and L, showing lower diglycosylated percentage, <50% for L-type, 3 replicates). H_B represents the H-type glycoprofile using a group B antibody (Sha31), not allowing a clear discrimination. The three-arrow symbol is to assist the reader in finding the direction of each point to the different axes.
