Figure 7.
RT-QuIC analysis showing positive prion seeding activity in MEF_Cer cells infected with white-tailed deer and mule deer CWD prions. Cell lysates were collected at different passages (P3 to P9) post-infection and RT-QuIC assay was setup as done earlier. (a–d) Show a positive seeding activity from passage P3 to P9 in cells infected with white-tailed deer (MEF_Cer_WTD) CWD prions as well as with mule deer (MEF_Cer_MD) 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.
