چکیده

Ice formation inside or outside cells during cryo-preservation has been proved to be the main cause for cryo-injury to cells. A high voltage DC electric field combined with a cryomicroscopic stage was used in this study. Dendritic ice crystals became asymmetric with the addition of electric field. DMSO and NaCl solutions were tested under different electric field strengths ranging from 83kV/m to 320kV/m. The shape change of ice crystals in the NaCl solution seemed more pronounced, because the NaCl solution was an ionic solution.

Multicomponent mixtures for cryoprotection and ligand solubilization☆

Mixed cryoprotectants have been developed for the solubilization of ligands for crystallization of protein-ligand complexes and for crystal soaking. Low affinity lead compounds with poor solubility are problematic for structural studies. Complete ligand solubilization is required for co-crystallization and crystal soaking experiments to obtain interpretable electron density maps for the ligand....

Numerical Study of Cell Cryo-Preservation: A Network Model of Intracellular Ice Formation

In this study, a new intracellular ice formation network model, coupled with an improved cell dehydration model has been developed. The non-uniform dehydration of the cell during freezing is simulated with moving boundary condition. Internal cell structures like cell nucleus are taken into consideration. The IIF network model is developed from classic diffusion limited IIF model in order to sim...
