  1. 3T3 cells were exposed to the listed buffers for 6 h at 37 °C and analyzed by phase contrast imaging. The averages and standard deviations are shown. V1, V5, percent of cells with ≥ 1 and ≥ 5 clearly visible vacuole(s), respectively; V2µm, the percent of cells containing at least one vacuole with a diameter of > 2 µm. Asterisks indicate statistical significance: * for 0.005 < p < 0.05, and ** for p < 0.005, by unpaired two-tailed t-test.
