Western blot characterization of the inocula used to inoculate reindeer and brainstem samples from representative reindeer from each experimental group in study of chronic wasting disease transmission. Scrapie prion protein (PrPSc) immunodetection using the monoclonal antibody 6H4. Positive Western blot results demonstrate a 3-band pattern (diglycosylated, highest; monoglycosylated, middle; and nonglycosylated, lowest) that is characteristic of prion diseases. Lanes: 1, biotinylated protein mark

Western blot characterization of the inocula used to inoculate reindeer and brainstem samples from representative reindeer from each experimental group in study of chronic wasting disease transmission.

Positive Western blot results demonstrate a 3-band pattern (diglycosylated, highest; monoglycosylated, middle; and nonglycosylated, lowest) that is characteristic of prion diseases. Lanes: 1, biotinylated protein marker; 2 and 3, indirect contact reindeer (animals no. 20 and 21, respectively); 4 and 5, reindeer inoculated intracranially with CWDmd (animals no. 15 and 12 respectively); 6, CWDmd inoculum; 7, direct contact reindeer (no. 7, cohoused with CWDwtd-inoculated reindeer); 8, reindeer (no. 5) inoculated intracranially with CWDwtd; 9, CWDwtd inoculum; 10, reindeer (no. 10) inoculated intracranially with CWDelk; 11, CWDelk inoculum; 12, marker. CWD, chronic wasting disease; CWDelk, CWD-affected elk; CWDmd, CWD-affected mule deer; CWDwtd, CWD-affected white-tailed deer combined with brain material from experimentally challenged white-tailed deer.
