FIG. 5.

Comparison of viable-count and microwell plate methods. Microplate wells were seeded as described in Materials and Methods, with Δtop2 α and 2M9HE in the media at five fourfold dilutions. All experiments, including control experiments, were performed in triplicate. The percentage increase in cell number relative to controls was estimated by viable-count and spectrophotometric methods. Error bars indicate one standard deviation.
