Those that recorded cell viability. For instance, Godon et al. looked at changes in protein expression after challenging exponentially growing wild-type YPH98 cells in synthetic complete dextrose (SCD). Izawa et al. and Bayliak et al. grew YPH250 cells in yeast extract peptone dextrose (YPD) but switched them to 100 mM potassium phosphate buffer, pH 7.4 (KPi) for the H2O2 challenge.
