Fig. 4: Effect of a high salt concentration on the water, Na-ion behavior, and cryopreservation.
From: Molecular mechanisms of cell cryopreservation with polyampholytes studied by solid-state NMR
a–c Temperature-dependent a ratio of residual water, full width at half maximum values for b the water proton peak, and c the Na sharp component signals of 600 and 1000 mOsm PLL-(0.65) solutions. d the cell viability after freezing with 7.5% PLL-(0.65) using various osmotic pressures. Error bars represent standard deviation.
