RT-QuIC analysis showing positive prion seeding activity in MEF_BV cells infected with white-tailed deer and mule deer CWD prions. Cell lysates were collected and processed for RT-QuIC analysis as done for Fig. 5. A positive seeding activity was seen at passage P3 to P9 in cells infected with white-tailed deer (MEF_BV_WTD) prions (a–d) as well as with mule deer (MEF_BV_MD) CWD prions (g–j). (e,k) represent uninfected cell lysate at passage 3 (negative control). (f,l) Represent 1% WTD- and MD-brain homogenate (BH) used as positive control for the assay.
