Analyses of cell viabilities receiving various plasmids expressing PrPs and/or TPPP.

<p>The cell viabilities of HeLa (A) and SHSY5Y (B) cells transfected with various plasmids were measured by a commercially Cell Counting Kit 24 and 48 h after transfection. Cells treated with colchicines (10 µM) were used as controls. The average data of each preparation was calculated based on three independent experiments and represented as mean ± S.D.
