Figure 1.

Charts displaying the relative effects of the various additives on number of live cells (a) or morphology (b). The y-axis shows t values of the absolute effects on the cells upon addition of various additives (x-axis). Blue or red bars: additives calculated to have negative or positive effects, respectively, on the number of live cells compared to storage without any additive. Filled bars = significance > 0.05 (not significant) No-fill bars = significance < 0.05 (significant). The figures are reconstructed in Prism Graph Pad from output in Design-Expert to improve clarity.
