Outline of Final Research Achievements

We synthesized partially carboxylated poly-L-lysine and discovered its cryoprotective property. This interesting phenomenon is characteristic of polymers with high electron charge, especially polyampholytes. We proposed that polyampholytes exert their cytoprotective action by protecting cells against stresses such as drastic changes in soluble space size and osmotic pressure during freezing by using solid-state NMR. Synthetic cryoprotectants revealed that the mechanisms related with the membrane protection properties of these polyampholytes by using liposome as a model membrane. The cryoprotective mechanisms are different from those of current available cryoprotectants. The novel findings might lead to the development of new effective cryoprotectants.
