Cryopreservation of Spin-Dried Mammalian Cells
Figure 3
Glass transition temperature of the dried spinning solution (1.8 M trehalose, 10 mM KCl, 5 mM glucose, 20 mM HEPES, 120 mM choline chloride, pH 7.4) using FTIR technique.
The figure indicates a characteristic peak-position of ν-OH stretch plotted against decreasing temperature.
