Treated cells were cultured in YPD medium and high pressure frozen in a Wohlwend Compact 3 machine, followed by a short freeze substitution protocol in 2% Uranyl acetate and embedded in HM20 resin. Sections of 70 nm thickness were then contrast stained with 2% Uranyl acetate and Reynold's lead citrate. Pictures were aquired in a Tecnai T12 TEM with a Ceta CMOS 16M camera.
